rotary grade laser / automatic / single grade

The first rotation laser with theft protection for all levelling work.

Simultaneous charging: the Li-Ion batteries in both components are charged together in very little time.
Calibration reminder: automatically indicates possible calibration requirement.
Relative height display: distance between where the laser beam hits the reception area and the centre of the receiver.
Slope function: enter slope values directly and precisely using the LR 50 Professional keypad.
Anti-Drift System: prevents levelling errors in the event of shocks or vibrations.
Sleep mode: longer operating time while retaining the settings
Centre Line button: automatically aligns the laser beam with the centre of the receiver and measures the slope value.

Theft protection: an alarm is triggered if the GRL 500 H/HV is moved without the LR 50 Professional during operation.
