Building bubble level. Building level how to choose

A good tool is a great help in any work, and a good building level is necessary in any household (mirror or cabinet hang), during repair. And for the construction of the bath you will need at least two or three different levels. The species of this tool are quite a lot and each has its own characteristics.

Bubble levels are the most popular. Most likely, it is caused by their not very high price and sufficient measurement accuracy. These tools are of the most different lengths - from several tens of centimeters to 3 meters. During construction or repair, there are usually levels of several sizes: short are convenient if you need to check the correspondence not small areas, and the long irreplaceable, for example, during plastering works, when installing the crate under the wall pane in the bath, etc.

Bubble levels have one, two or three transparent chambers with a scale filled with a bubble liquid. According to the position of the bubble relative to inflicted divisions and determines the deviation from the vertical and horizontal. If the tool has only one chamber - only the horizontal surfaces can be monitored if the cameras are vertical and horizontal. There are levels and with three flasks. The third, if it is fixed, serves to determine the deviation from an angle of 45 degrees. But there are models with movable flasks that allow you to determine the deviation from the selected angle of inclination. Such will be needed when erecting a rafter system and some other works.

There are several modifications of bubble levels: some of them are mounted magnets and it is convenient to fix on metal surfaces. Such levels are also called magnetic levels. There are special tools for masonry and tiler: There are places for which you can knock the hammer that is very convenient.

How to choose a bubble level

Larction of prices for these tools is quite large. Definitely, buy the cheapest hardly worth it, except that you need them for one-time work. If you have to build or serious repairs, it is worth choosing one of the professional levels. Though they are quite more expensive, but also to serve will be much longer: there are thick-walled corps, for which shocks and falls are not so scary, some are equipped with rubber linings that soften the blows. The level of construction Stabila has proven it better. The KAPRO tool is not bad (the manufacturer gives a lifelong warranty on the flasks) and Kraftool. This is probably the best building levels from the market available today. If we talk about the average price category, the "bison", Stayer and Matrix have proven well well.

Choosing a tool, pay attention to the fastening of the flask: they should not be fused. It is better if they are mounted tightly, without screws. At first glance, the flasks fortified with the help of screws are good because they can be independently adjusted, but in practice such tools are very quickly knocked up, and it accounts for the entire setting procedure to repeat again and again. In order to work the level it was convenient, you should see the flask well, fission on it and the position of the bubble. The farther from each other, the strips on the flask are removed, the harder it is to determine how shifting the bubble.

Important! Even after a minor fall, the bubble level can begin to "lie", especially for cheap models. For this reason, check the level of reading accuracy right in the store.

How to check the bubble level

To check the accuracy of the level, you need to put it on any horizontal surface (for example, on the storefront in the store), notice the place where it lies, and remember the position of the bubble. Expand the tool for 180 o (the part that was right should be left), install in the same place and look at the position of the bubble. If the testimony coincides, the horizontal flask is exhibited correctly. Repeat the same check on the vertical plane (for example, on the wall). If the testimony coincides there, this level can be bought. If somewhere there are deviations, ask another.

For details on checking the bubble level, see the video.

Laser construction level

Laser building levels are the most modern and accurate, but also the most expensive. The most budget options are as much (or more), how many professional bubble levels. But this is a compact device that is attached to any surface and has a range of up to 100 meters. Laser levels allow you to perfectly expose straight, some models have a function scanning of the direction in the plane, there are cross-models with 2 or more (up to 10) lines, with which you can perform any work. The only drawback is a big price.

The world leader in the production of laser levels is the German company Bosch - it produces a huge line of laser levels. Compact models include the Bosch PPL5 model.

This device is quite compact, which you can make sure to look at the video.

The laser level can be fixed on the wall, and on the guide glue the tile on the walls in the bath or sauna.

If you are not a professional builder, it is sinking the need to buy expensive levels to which Bosch products belong. If you need a laser level only to build a single bath, it is quite possible to buy a laser level in China. The price of such a level on eBay is only 8-9 dollars, and the delivery to Russia is free.

For the laser operation, three "Tablet" type batteries will be required.

Water or hydro-level

This tool is suitable for determining the presence of deviations of horizontal surfaces. Neither the vertical, nor the plane located at the angle of them can not be checked. Water level is a set of hose (from 5 to 25 meters long) and two glass flasks with a scale applied to them.

Water is poured into this design (it is necessary to pour water temperature water and watch that bubbles are not formed). Draw a horizontal line, you can exhibit the same water levels in both flasks.

Water levels are conveniently used when working with large surfaces (for example, when booking the foundation or piles), but they are uncomfortable when working in small rooms. Their main disadvantage: sensitivity to temperature drops: It is impossible to check the surfaces that are less than 1.5 meters from heating devices or other heat sources.

A huge advantage of water levels is that, with proper use, you can perfectly extorter the horizontal at large planes. For this reason, for marking, it is desirable to use the water level, and not bubble.

When buying a hydraulic system, check that there are no cracks on plastic flasks.

Pipe Levels

They work on the principle of bubbles, but have small sizes and most often performed in the form of a rectangle. Some models are folding.

It is convenient to use them when working with pipes or when laying profiles (some have appropriate holes and / or magnets so that they are more convenient to fix).

Species of levels and their different modifications a lot. The main thing is to determine for what purposes you will use them, and to choose the most appropriate option.

Level on android

What progress has come about ... This is exactly what I want to say when you know that you can now download and install the construction level program on the device running android operating system (Android).

Program construction level in the smartphone

There are already quite a large number of such programs, but there are not much quality of them as much as you want. One of the most popular levels for the smartphone is the program. Bubble Levelwhich can be installed by passing at this link https://play.google.com/store/apps/details?id\u003dnet.androGames.Level&hl\u003dru.

The BUBBLE LEVEL program allows you to switch the type of level.

Bubble Level program allows you to switch level view

The smartphone is oriented in space using the camera built into it. After installing the program, you must calibrate the device to put it on a flat surface.

As you understand, the level for android cannot be considered as a full-fledged tool when building a bath. Although using this level, it will be quite possible to hang pictures in the rest room.

conclusions

When building a bath, like with any other construction, without a construction level can not do. Since our site is designed for amateur builders, we must propose the next gentleman's set:

Hydroelectory (required);
Bubble level (required);
Chinese laser level (you can and do).

All this set can be bought in just 1000 rubles and it will be enough when all types of work starting from the fill of the foundation and ending with the tile laying.

Greetings to you, dear visitors! For the last couple of days I thought about the topic for the article, and then I came an email from one reader in which he asked to tell about the construction levels. And I thought - and an excellent thought. After all, where to repair without a level?

To date, the choice of levels is simply epic. From the simplest water to digital with a built-in laser. What level and for what purposes is needed, and also for what criteria to choose them - find out right now.

Construction level: Types

The most simple constructively is an ordinary water level, it is a hydrorette. It is two plastic usually cylindrical flasks with a scale connected to each other flexible long hose. The principle of his action is simple and should be understood by any high school student. It is based on a well-known physical phenomenon - the water level in the reporting vessels is always the same.

With this device, we can easily mark two points in one horizontal plane at the maximum distance equal to the length of the hose. You just need to put the marks in front of the water boundaries in the flasks.

Such a tool will be indispensable in the construction of a country house, markup of ceilings and floors when repairing and similar things. The length of the hoses of such levels lie in the range of 7 - 25 meters, which is quite a few. The cost of such a tool, understandable, is small, in the area of \u200b\u200b150 - 300 rubles.

It is more convenient to work with flasks of non-cylindrical shape, but with rectangular in cross section - it is easier to apply them to the surface. The diameter of the tube is the more, the faster the same level is installed in both flasks. As a rule, hydroeers have a diameter of 6 - 8 mm.

The following instrument class - bubble levels or waterpasses. Most has a length of 40 - 250 cm. The horizontal and the vertical in them is controlled by the position of the air bubble in alcohol, soldered in special transparent flasks. Short Waterpasa need when laying tiles, windows and windows mounting ...

Long - for setting beacons, check vertical / horizontal planes and lines, different marking. Oddly enough at first glance, Waterpasi may differ in many characteristics that we will talk more in more detail in the next chapter.

Cornelters and biasmen are devices that allow measurement and set the angles between the planes, and the slopes of the planes from the horizontal and vertical, respectively. Such devices may look different. Cornelizers are in the form of a quarter of a round of a circle and in the form of two "rails" connected by a hinge, or how it is there.

Basically, the angles and the bias are digital devices, that is, there are an LCD display where the angles are displayed. The inclusion is also often called an electronic or digital level.

I think that the tomitors are needed, mostly not builders, but to carpenters. They also will be more useful. In the finishing, the inclusiveness will only be in demand, perhaps on tile work, and more for control. Their highest accuracy (usually 0.05 degrees) does not leave the tile chance even on the smallest halter. And you will most likely beat up on the second or third tile))

My colleague, tiler, recently acquired a Bosch digital inclusion and confirmed it. But, the hell, how he is cool, this bosch.

There are also different avant-garde types of construction levels. For example, tube. They, besides, are still in different design. There are devices in the form of "hairpins", wear on the pipe, there are ordinary bubbles with a notch under the pipe on the housing, and there is generally the masterpieces of the avant-garde - "sticks" with five eyes, each of which is configured to a certain slope - to make it easier to conduct a sewer, you see Lee.

Laser levels. I already have an article about them, so I will be brief. This is the most technological look (I mean self-leveling). High accuracy, ease of use, huge time saving when marking. Such devices are divided into two large classes: positional and rotary.

Positioning does not have any moving mechanisms, as a rule, give a classic laser cross, or several points.

Rotary lasers provide one point, but it due to the spinning base quickly moves 360 degrees. Such instruments are used, for example, masters-ceiling.

Select bubble level

Of course, the most common tools for home repairs are bubble. So what criteria are the most important when choosing Waterpas?

First you need to decide what works you need it. From this will depend on the length of the tool. If for the tile, then you will not do with one level, you will need at least two: short (40 or 60 cm) and long (200 cm). Short is used constantly to check the level between adjacent tiles. Long - to control the entire facing plane.

If you intend to collect designs from GLC, plaster, pour the screed, you will definitely need a long Waterpas, at least two meters.

The next most important criterion is a form.

There are often levels in cross section representing rails. This is not the best choice - such a tool is very nervous. Much more powerful "stick" of a box type. And if inside them have a ribbiness - it is generally great!

The next point is the device of the flask.

Extremely important feature. In the store you can see the levels, let's say with such flasks:

What do you think, in what case of the instrument readings will be more accurate? Of course, in the first. The smaller the distance from the borders of the bubble to the divisions of the flask, the more accurate the deviation can be determined. Remember this. Also pay attention to the sensitivity of the bubble, it strongly depends on the radius of the curvature of the flasks. It seems to the eye that the flask has the shape of the cylinder, but it is not entirely so, it is a bit twisted, otherwise the slightest deviation from the horizon "carried out" would be a bubble to the most edge of the flasks.

Here you can add another one. The flask for determining verticality is often unavailable for a good review, because Having attached the construction level to the wall, we will not be able to look at the level of the level parallel to it - the head interferes. So, we will not be able to objectively judge the testimony of the device. But there are levels in which a special mirror system is built, and the image of the flask "is output" to the rear end of the level, which is extremely convenient. Such a system have, for example, Israeli levels of Kapro Plumbsite series.

The accuracy of "sticks" for professional use is not worse than 0.5 mm per 1 meter length, and the tool is suitable for work on the house, with an accuracy of 1 mm per meter.

Processing workspaces. Ideally, they must be treated with a mill. This can be understood on a rough surface (-th).

The presence of embedded magnets is also a very important addition to any level. Having hung him to the profile and calmly regulate it. Even extremely useful "chips" of Waterpasov are slits in the building for the convenience of grip and rubberized lining, often employees also by shock absorbers in the event of a tool drop.

Rotary and adjustable flasks are controversial advantages. Tools for which manual adjustment is available instead of the "dead" fastening, most likely will be born. It is better to take once and forever sealed flasks. The main thing is to carefully check the tool in the store.

The verification procedure is quite simple. Put the level first on the table or counter, look at the testimony, remember. Then rotate 180 degrees (but that it remains in the same place!) And look again. If the bubble position is the same - the tool is not lying. The same procedure is done for the vertical, only attach it to the wall.

In some Waterpasa, the flask for controlling the horizontal is recessed in the middle. Personally, this decision seems uncomfortable to me, and I do not advise you to acquire a similar ***. The flask must be top, and the point.

Here is a good video about bubble levels:

Well, here, I told everything that I knew. Do not buy a frank cheap, carefully inspect the tool before purchasing. On this article is over, thanks for your attention! And do not forget to subscribe to updates.

In this section of the online store SKLADOM you can buy a building level at a low price! Our catalog presents a wide range of. The range includes tools manufactured in Russia and abroad. A rich selection allows you to find the best option in terms of cost and functional purpose that allows you to solve problems of any degree of complexity.

Types of construction levels

We can buy a building level:

Bubble. Special rectangular tool with mounted transparent flasks filled with liquid. By location, the bubble is easy to determine the correspondence of the surface of the horizontal or vertical plane. The presence of an third flask makes it possible to measure the degree of deviation from the specified horizon parameters. The catalog presents the levels of different lengths and execution of the case: "profile", "rail", etc.

Water - a special building tool. The level is designed to determine the horizontal location of structures or remote items. Two graded flasks at the ends of the hose filled with water, allow the bag and accurately repel the horizontal level of the foundation, screed, floor, etc.

Correctly choose the level will help photographs accompanying each model, as well as an informative description. Enough to go to the site page and you can learn all about the possibilities, advantages and distinctive features of a particular model.

Depending on the type of tool, the manufacturer and individual characteristics, the level of the construction price may be different. Along with professional, more expensive products, we have and budget models that are beneficial to available costs and high quality.

For accurate and fast measurement, buy construction levels in Skladom!

The right choice of measuring instrument significantly improves the quality of work and saves time. By design, five main types of building levels can be distinguished: bubbles, electronic, pipe, hydraulic, laser. Below we will look at each of them in more detail.

Five types of construction levels

Bubble levels They got the greatest distribution due to their simplicity, availability and versatility. They are called so because they have a sensitive element of air bubble floating in ampoule. The error of measurements of these devices is 0.5 ÷ 1 mm / m. Domestic models are manufactured according to GOST 9416-83, which describes the technical conditions for their manufacture. The body of the tool is a hollow boxed design with rigidity ribs. It can have a length of 30 cm to several meters. To reduce the mass, the device is made of aluminum alloys. Ampoules with air are closed with protective glass. At the base of the case, as a rule, there is a millimeter measurement scale.

Magnetic bubble levels are perfect for working with metal structures. Their distinctive feature is the presence of built-in magnets that allow you to fix the tool vertically on metal details. For masonry, there are models with a reinforced cast case. If you are coming plastering, pay attention to the rules with the level. They combine two devices in themselves at the same time.

Electronic levels A teller belongs to a professional measuring instrument. They have several bubble chambers to estimate the verticality and horizontal structures. However, in contrast to the usual levels, such devices have a number of additional features.

One of the main features is a digital display, which clearly displays the deflection value in degrees. In this case, the accuracy of the data provided is high - to 0.1⁰. It is possible to record measured slopes. A sound indication is provided that signals the achievement of 0⁰ and 90⁰.

Checking the accuracy of the electronic level is simple and does not take much time. To do this, you need to put the device on a flat surface, withdrawn. Turning a level of 180 degrees, to see new meanings. If the difference in readings is more than 0.2⁰, the device is calibrated.

Designed to check the horizontal and verticality of water supply, gas, sewer pipes. In general, it is convenient to use it for working with beams, a round profile in various building structures. The main features of this tool are the V-shaped shape of the hull, the presence of magnets. Thanks to this, the instrument can be easily installed on a metal pipe or support.

The pipe level, as well as bubble, is equipped with several flasks with alcohol liquid. In each of them floats the air bubble, by the location of which the deviation from the specified direction is determined.

Used to apply accurate horizontal markup on the objects deleted from each other. With it, they make a panel of flooring, the installation of the foundation, the brick laying, the installation of various building structures in the same plane.

The hydrostatic level consists of two vessels interconnected by a transparent tube. Before working, the system is filled with water so that it occupied approximately 2/3 of the volume of the flask. At the same time, the fluid inside the tube does not contain air bubbles. They need to be removed, otherwise the measurements will be inaccurate. Negleps and fractures of the tube are not allowed: water should flow freely from one vessel to another. To check the accuracy of the device, the flasks combine each other. It is necessary that the boundaries of the liquid have a common one.

Industry produces hydrostatic levels from 5 to 25 m long. The error of measurement of these devices is 2 ÷ 3 mm. Marking is recommended from one basic tag. This allows you to achieve maximum accuracy.

Laser building levels (Leveliers) refer to the group of professional measuring instruments. Despite the fairly high cost compared to other solutions, they provide their owner a number of advantages. First of all, it is a high accuracy markup. The magnitude of the allowable deviation is only 0.1 ÷ 1 mm / m, depending on the class of the instrument. The technical capabilities of linear laser levels allows them to build horizontal, vertical, as well as inclined planes at a distance of several tens of meters from the installation site. For home use, this is more than enough. Rotary laser levels Thanks to the rotation of the emitter, the rays across the perimeter of the room are projected, that is, cover the entire space around itself.

What construction work is conducted using laser levels:

alignment of walls or floor;
installation of mounted equipment;
wall pastry wallpaper;
installation of stretch ceilings;
facing of premises tile;
installation of partitions and others.

To repair efficiently, before the start of work, choose a good measuring instrument. Now there are a wide variety of building levels. They differ from each other by appointment, technical characteristics, manufacturing quality and price.

What task is before you?! If an inexpensive universal tool is needed for all occasions, it is worth paying attention to bubble levels. They are comfortable, unpretentious, and most importantly - have good accuracy. Their capabilities are enough to put the tile, install windows, doors or furniture. The length of the universal level is 60 ÷ 80 cm.

Electronic levels with a tilter and magnetic system will suit those who decided to repair seriously. They have advanced features. First of all, this is a visual representation of data on an electronic display with an accurate indication of deviations in degrees, percentages or millimeters. Other distinguishing features are high accuracy, the reading function, as well as the possibility of electronic calibration.

If you need to align beams, pillars, plumbing or gas pipes in vertical and horizontal directions, use all the advantages of pipe levels. Their indisputable advantage is the possibility of accurate centering on these elements of building structures.

The water level will be useful when the floor screed device, the mounting of the suspended ceilings, the foundation device. It will come in handy for marking places for the socket, which will look aesthetic, being at one height. Water level can perform accurate horizontal marking for related rooms, between which there is no direct visibility. This consists of one of its main advantages. This tool has low cost, easy to operate. Its length varies from 5 to 25 meters, which is quite enough for domestic use.

The laser level will be an excellent choice for those who have a large amount of construction work. It will significantly save time, while ensuring the high accuracy of constructions of both horizontal and vertical planes. This is a good tool for blending the floor level, wall markup for finishing works, installation of furniture and communications.

Three main types of laser levels can be distinguished: point, linear, rotary. In accordance with the title, they are used to build dots, lines, as well as markups throughout the perimeter of the room at the same time.

Before starting work, laser devices must be aligned with the built-in bubble level. Some models have an additional self-configuration function within 2 ÷ 4 degrees. The price of professional laser levels is high enough, however there are available options for home use.

What to pay attention to when choosing

Among the large number of manufacturers present in the measuring instrument market, there are those that have already managed to conquer an excellent reputation in our country and abroad. In a good account, builders are bubble, as well as electronic levels of Stabila and Kapro. Bosch laser levels are known for their quality. However, it is best to rely on your own experience in order to purchase a thing with the necessary set of functions for reasonable money. Basic selection criteria: specifications, equipment, quality assembly and materials.

By purchasing a bubble level, it is necessary to inspect its appearance. Are there any visible damage?! What are the quality of the materials, is it carefully assembled?! Special attention should be paid to ampos with liquid. They must be securely embedded in the housing.

Put the selected level on a smooth horizontal surface. It must be tight, without gaps to lay down its base. Remember the position of the air bubble in the upper ampoule. After that, turn the device to 180 ° C clientwise or counterclockwise and place the same place. If the bubble has shifted relative to the initial position, it is impossible to trust this level. Similarly, you can check the accuracy of the readings vertically.

A bubble level is an indispensable tool for the construction and repair work of various types. This device helps to create smooth lines in any plane, check the required slope or corners. Straoters of building levels are plumbing and waterpasses whose functions they are essentially performing. Levels are indispensable when laying pipes and various surfaces that are demanding on the angle of inclination. They are used during the installation of technician, which vibrates when working and demanding to the evenness of the installation surface. The arrangement of waste pipes or steps is also not done without this tool. Building levels are in the arsenal of any master and are the necessary thing in the farm, because it is important to know how to choose the construction level.

Construction of bubble level

Construction level The bubble is a fairly simple, but functional design. It is based on a strap from a solid material into which a number of ampoules with air mounted. The ampule causes measuring labels for which the position of the air located inside it is determined. This is this indicator and is the key to the level of level. When the bubble is located exactly in the middle, this means that the surface is perfectly smooth. To check the inclined surfaces, use the air deflection indicator relative to the center of the ampoule.

The main and most important part of the level is an ampoule with a liquid in which the air swims. If you break the integrity of this part, then the entire device is considered unsuitable. By filling the ampoule, the technical alcohol is most often. For ease of use, manufacturers modify the level, some models are equipped with a lens that allows the worker better to see the bubble. To work at night, fluorescent additives are fastened to the liquid, helping their glow to use the device without additional lighting. In such improved models, the ampoule with all additives is called the eye.

Shockproof models were quite popular. During work at a construction site or during the transport of the device, unpleasant cases are often occasionally occasionally - drops, shakes, mechanical damage, which are due to the level. Long modifications are often broken, since their size increases the likelihood of falling and makes the shock force greater than that of the models with a short frame. At this level, the construction price is slightly higher than on ordinary models. However, it is still more profitable to buy a shockproof device than to regularly replace new spoiled.

The basis is no less important in the whole design. It consists of wooden, plastic or aluminum planks. Wooden planks are made of solid, aluminum or plastic hollows. Most often there are levels with an aluminum basis. When choosing a device pay attention to its weight, as the heavier the device, the better his testimony. Practicing specialists among all modifications allocate the design of the cross-shaped form with rubber handles. They call such levels the most comfortable and accurate. To work with metal surfaces, it is recommended to use equipment equipped with magnets. Another option is not a mandatory, but a convenient addition is a line on the long side of the level. Such a modification will help out when measuring operations and will exclude the need to have a ruler or roulette.

The simplest and primitive level model has only one measuring ampoule. But such modifications are quite difficult to find in a modern store. Manufacturers are offered in a larger range of levels with two or three ampoules. One of the tanks is located on a long wide side and is designed to work in a horizontal plane. The second container is located on a narrow short side of the device, perpendicular to the first. It is designed to work in the vertical plane. If there is another container on the bar, then it is also located on a narrow part, but on the reverse side. Fasten it at an angle of 45O, and the assignment of this ampoule is to control the operation of the device.

Bubble levels Manufacturers offer not only in different modifications, but also of different lengths. The shortest standard model has in the long part 20 cm, the longest is 3-4 m. This indicator defines the functional purpose of the level. To install various household appliances and performing simple repair tasks in a private house or apartment, it is enough to use low-size levels. When laying a tile or working with various finishing materials of this type, the length from 40 cm to 1 m is optimally suitable. Long construction levels are professional, used when carrying out large construction and repair work. Experts note that the larger the level of level, the more accurately its testimony.

What to pay attention to when buying a bubble level

Building levels are one of the most popular products from manufacturers of cheap and low-quality products. Since this item is used not only by professional builders who know exactly what they need, but also ordinary people. The construction technology technology is not as complicated, but requires the accuracy and use of high-quality materials so that the device worked properly. Unfortunately, manufacturers of fakes and low-quality goods enjoy the ignorance of unqualified in matters of the construction of people and offer poor-quality products, which are not accurate. Trading stamps that have already proven themselves as responsible manufacturers of building levels:

Kapro.

Stabila.
Ermak
Bosch.
Gross Laser.
Shark (Israel)
Leader

But, even focusing on these names, it is not always possible to buy a qualitative and durable construction level. You need to know some nuances of choosing this device, as well as be able to determine the desired model, so as not to overpay the extra money for the professional level in the event that it is only necessary for carrying out small household work.

To begin with, it is determined with the necessary tool length. For this, define the goals and objectives that are set in front of it. For finishing and leveling surfaces, you will need a long-length device. For small decorative works - installation of suspended furniture, shelves, switches, paintings There are enough levels of small or medium sizes. The most optimal option for use in living conditions is a level 50-60 cm long.

During the choice, all the glass elements of the device carefully examine. We are talking about tanks with air that perform the main function. First of all, they must be integer and not have traces of mechanical exposure. Next, the strength of their attachment is checked, the data of the parts are fixed tightly and should not be fused or unscrewed. There are models with the possibility of adjusting the containers, the presence of this feature is a very controversial point. On the one hand, adjustment allows you to customize the failed level, on the other side it makes the device more vulnerable to shakes and mechanical effects. Professional builders recommend purchasing levels with rigid fixation of all tanks.
After inspection of the fixation, the flasks pay attention to the air itself and the strip deposited on the surface. All these elements should be clearly visible and located close to each other. The optimal option is the location of the control strips inside the bubble, and not on its outer surface. Since with active use these labels will quickly erase.
Next important factor - level base material. Regardless of whether it is made of wood, plastic or metal, it should be heavy and durable. Optimal models with rigid ribs located inside. In general, the design and external level design differs from each manufacturer, but this aspect does not affect the accuracy of the device itself.
After the external inspection of the level it must be checked. In specialized stores, there should always be a stand for checking a device that has a perfectly smooth surface. But even if there is no such stand, it is not difficult to check the level in any other place. To do this, it is placed in a horizontal plane and the position of the air bubble is marked. Even if it deviates from the center - it is not scary, since the essence of this check is not in this. Then the level is raised, turn on 180 ° and put smoothly at the same place. At the same time, the position of the bubble should be on the same mark. If so, then the device is properly.
Accuracy of the reading of the smooth plane without the presence of a proven surface cannot be. But in this situation it is enough to save the check from the product and then check the level readings using other devices. For example, this uses a level or laser level, or a bubble, which has already proven its testimony. These checks must be carried out even with branded and expensive things, since during transportation the technical specifications and device readings are often violated.

How to set up a bubble level

The configuration of the bubble level is possible only if the model with unlocked tanks is available. The level of level setting is simple enough:

The most flat wall in the room is determined, this area must be at the level of the eye, the angle at the same time is located on the left side.

Rates from the angle of about 4 cm, driven a nail or spin self-tapping. Do it not to the end, and so that 2-3 cm remains not the surface.
The device is placed one side on the nail and lean to the wall, and then adjust it so that the air in the container shows a flat surface. On the edge of the level on the wall, fill the line.
Turn the device and repeat the procedure.

The correct setting is checked according to the declared lines, if they do not go beyond each other borders, the device functions properly and its readings. If the fascinated marks diverged, then it is necessary to act as follows:

On the right side, where the marks end, mark the central point between them.
The device is placed on a nail again, and another end is applied to the marked point.
For convenience, another self-tapping screw is screwed into the mark, or simply hold the level of hand.
In the fixed position, adjust the container with the liquid to the required position.

In the same way, the container is also adjusted for operation in the vertical plane, only the level is pressed against the nail with a long side.

When working with a building level, it is important to remember that this device has a working surface, which it is applied to the control portion. This area is distinguished by the untreated edge or magnetic insert. In some models, the differences between the working surface and other faces are not. If you use the device with the other side when using the device, it will not harm it, but the measurement accuracy will fall. The level never put sideways, all the measurements produced in this way are not correct, since, in fact, a non-existent surface is measured.

To work in the horizontal plane, focus on the container in the long side of the level. The device is applied to the surface and mark the line in which the air was exactly in the center of the ampoule. If there is a deviation to the left, then slightly lowered the left edge of the frame or lifted right. Similarly, they are in the right side of the abnormalities.

To work in the vertical plane, focus on the tank in a narrow face of the device. For example, if you need to check the quality of the wall finish, the device is applied to it with a container up. If the air leaves from the wall, there is a convex irregularity below. If the air is moving towards the wall, then it means you need to add a bit below the level below.
