Leveling is called a device that allows you to determine the smoothness of the surface. The most accurate devices for determining the level are laser levels. Such a ray is as concentrated as possible and allows you to display all the existing irregularities of the surface.
Levelers are rotational and prismatic. The choice is influenced by the tasks required from these devices. There are no moving parts in the prismal level and it is considered a more reliable. With it, most of the work is performed. Such a leveling level perpendicular to the right angle projects two laser rays.
The rotational level gives more opportunities for projecting. He has a large range of actions, and this allows you to align huge areas. Therefore, it is advisable to use it at large construction sites. The range of such a device reaches one kilometer. Three times the larger angle of deployment allows you to align in such inaccessible places as window openings or doorways. If you have such a task, it is more convenient to use rotational levels.
Type of alignment will also affect the quality of the work: manual or self -leveling.
The use of a self -leveling leveling level eliminates the likelihood of an error due to the human factor, therefore it is used everywhere. The self -leveling range is often about four degrees. This is enough to carry out the necessary measurements. In the event that self -leveling is impossible, the device emits a special signal that says that it should be changed for normal operation. This moment is important, since in calculations the key role can be played by incorrect calculations.
These are the main criteria by which laser levels choose. Everything else depends only on you.
