Laser levellers for Machine Control Systems

Automatic laser levelers GL700 from Spectra Precision (USA) are designed for precision leveling in construction and engineering in small, medium and long distances. Suitable for horizontal work. Provides work on two oblique planes. It is designed for outdoor use with handheld and GCS900, GCSFlex, etc. machine control receiver systems.
         During operation, the instrument keeps track of the height of the parking space. This control remains in the standby mode.
         Protected against falling from 1m height on concrete.
The GL700 is equipped with a laser beam receiver HL700.
         The whole set fits in a durable, bright yellow plastic carrying case.
Basic use of the level series - working with laser-powered machine control systems.
