For the construction process, one cannot but use the necessary and necessary tool as a level. It is used to determine whether there are between two points or a gap of criticism relative to a certain level. Recently, Bosch levels began to be widely used. They are a quality tool and therefore they are used by both professionals and ordinary beginner builders and lovers.
Novelty are considered levels with laser devices. This property greatly facilitates work in large territories and with huge height changes. This greatly facilitated the task of builders when using the level and line is simply impossible. The laser beam is extremely accurate to measure, with the exclusion of curvature and bending of light.
At the construction site, the level is used for various purposes. According to this definition, the tool is divided into such types:
Laser (with the help of a ray determines the differences both outside the room and in its middle);
Optical (use at objects where it is necessary to determine greater accuracy);
Hydrostatic (work on the basis of the liquid located inside);
Geometric (work on the basis of drawings using a conventional line);
Barometric (measurements are carried out using a barometer);
Trigonometric (based on the use of vizier lines);
Radar (application for measuring echolocators).
Relative height is determined by levelers, that is, the difference between points relative to each other. The most popular use of laser and optical levels is in geodetic works. Now those measurements that were almost impossible to make have become a common process for builders. Some levels are equipped with several lasers at once, which allows you to simultaneously take measurements in different directions and create the effect of the volume of space.
