Peculiarities
During the construction, repair, reconstruction and redevelopment of buildings and premises, the role of the building level is very important. For work at home and in the country, you can do with household products. But for permanent use (for example, in the practice of a freelance electrician or bricklayer), you must immediately focus on professional equipment. This is precisely the products of the Middle Eastern company Kapro, which has proven itself from the best side.
As befits a good instrument, these levels are highly accurate. Unlike inexpensive goods from Southeast Asia, Kapro equipment will not fail even after being dropped or bumped. Even the most careful builder or repairman will not be able to avoid such incidents. Speaking about the advantages of levels from Israel, it is worth noting:
- lifetime corporate warranty on them;
- minimal risk of discoloration of the flasks;
- no risk of fading;
- reliable fastening of all main parts.
Selection recommendations
When choosing a bubble level, be sure to pay attention to its flask. Its complete transparency and the absence of the slightest defects, even abrasions are required.
Then you need to evaluate how well the bulb is secured. The stiffer the fixation, the higher the reliability of the device.
It is very important that all lane lines are perfectly clearly traced.
It is imperative to find out how correct the readings of the device are. But its length (40, 60, 80 cm) is determined only by personal convenience and practicality. Novice builders and repairmen can take a level of any length. All the same, later it will have to be replaced with a more perfect product. The laser level should be equipped with a special reinforced case and a telescopic tripod; professionals prefer models with a mirror.
Types by method of work
No matter how solid the warranty is provided for such products, the principles of their operation must also be taken into account. Sometimes the device does not cause any technical criticism, but it is simply unsuitable for certain measurements in a certain situation. Most often, a bubble level can be seen on a construction site or during a renovation. This tool has a simple structure, but at the same time it is quite functional and convenient.
Many have seen a rectangle with an inner cavity. The middle of the device is occupied by a transparent flask. In professional jargon, it is customary to call it "peephole". The name of the type of instrument is simply explained - there is technical alcohol or other low-density liquid in the flask, and an air bubble floats in the liquid, the vibrations of which are used for measurements.
In kits for professional use, so that builders do not waste time in vain, the liquid is colored. Recent developments even include the use of fluorescent additives to make it easier to work in the dark. The flask is marked with stripes perpendicular to the main part of the level. These bars indicate deviation. When the balloon is located exactly in the middle, the surface can be assumed to be perfectly aligned.
It should be borne in mind that an increase in the size of the bubble and a decrease in the distance from it to the boundary lines contributes to an increase in the accuracy of measurements. In some models, this indicator can even be customized at your discretion. Most bubble levels use two flasks at once, allowing you to track the evenness of the vertical and horizontal lines, respectively.
Modern bubble equipment can be equipped with:
- stiffening ribs;
- marking one of the surfaces;
- milled surface;
- a platform for striking;
- pipe grooves;
- magnet at one end.
In addition to simplicity, bubble levels are good because they can be used in everyday life and in professional practice. Even inexperienced beginners can work with such systems. Thanks to the wide range of sizes, you can choose the version with the ideal parameters for a specific task. Bubble instruments are inexpensive. However, they still suffer greatly from any fall or collision, and the adjustment options often go astray.
Pipe levels from Israel are used very rarely. They are needed to lay various pipes, profiles and beams, the cross-section of which usually does not exceed 100 mm. Structurally, there are no special differences from the bubble instrument. There are several flasks with liquid, but the body is always V-shaped and equipped with magnets. Some pipe levels are complemented by a collapsible, removable clamp just for the diameter of the pipe being used.
Hydraulic levels are needed when it is required to apply horizontal markings as accurately as possible. This tool is suitable for:
- installation of ceilings;
- markings of future floors;
- construction of foundations;
- other extensive surface works.
Features of hydro levels:
- are cheap;
- can be operated even without special skills;
- almost not destroyed by blows and falls;
- do not need special calibration;
- can be used only by two people and strictly at a positive temperature;
- not suitable for measuring planes and lines in a vertical plane;
- not very convenient in terms of filling with liquid.
Electronic levels are used mainly by professional builders and repairmen. They are designed for particularly precise measuring work. Outwardly, there are almost no differences from the bubble variant. But there is a goniometer and a digital standard display that allows you to determine deviations. They are measured not only in degrees, but also in millimeters or in percentage terms - as the consumer wants.
Electronic levels:
- very accurate;
- used without any problems;
- can remember previously measured slopes;
- have sound signaling;
- need systematic calibration;
- require careful handling;
- are very expensive.
The laser level is another professional device. Its alternative name is level. They construct virtually planes (not only horizontal or vertical, but also inclined ones) at a distance of up to several tens of meters. Therefore, such devices are very valuable when you need to mark something, align walls, mount stretch or suspended ceilings, build or move partitions.
