From the moment of its appearance, the level of geodesist, which is used in construction, during installation work. The possibility of its use in finishing work appeared only with the appearance of laser levels and rangefinders. Works such as laying ceramic tiles, parquet, installation of drywall partitions and suspended ceilings require high accuracy. Discrepancies of several millimeters reduce to zero the quality of work performed and require significant efforts to eliminate and mask defects. The time of time for measurement and marking is comparable to the duration of the work itself. Laser levels provide such measurements in a short time and with high accuracy.
A special mounting design allows you to fix a laser level on any surface – a wall, ceiling, column. The attached device is ready to work immediately after turning on and automatically builds a plane in the required direction. The main advantage of laser levels is that they make it possible to visually view the vertical, horizontal or inclined working plane.
The range of devices used for finishing work is 10-40 meters with an accuracy of 0.1- 0.3 mm // m.
The usual mechanical roulettees used before the appearance of laser rangefinders require two performers to work and conduct a large number of measurements. The named laser roulette laser rangefinder allows one worker to make the necessary measurements with high accuracy in the minimum time.
Disto laser distance meters from 5cm to 200 m with an accuracy of ± 0.5 mm, which of course is incomparable with the accuracy of a mechanical roulette. There is a function of execution of size in nature – with a given size, as soon as the laser spot is at a given distance, the sound signal sounds. It is noteworthy that all measurements taken remain in the memory of the device, and the function of measuring the area will determine the number of tiles for each measured area of the wall.
