Laser distance meter LDM301 (Astech)

Attention:

LDM301 is equipped with two laser. The infrared laser for measurement operating at 905nm is a CLASS 1 Laser Product which is safe under reasonably foreseeable conditions of operation. The pilot laser is a CLASS 2 Laser Product operating in the visible red light at 635nm. It is not eye-safe!

DO NOT LOOK INTO THE TRANSMITTER LENS!

DO NOT POINT THE TRANSMITTER LENS AT OTHER PEOPLES EYES!

DO NOT LOOK AT THE LASER BEAM USING OPTICAL INSTRUMENTS!

Summary

The laser distance measurement device LDM301 enables the non-contact measurement of distances. The measurement range depends on the reflectivity and the surface of the measuring target. It ranges between 0.5 and 300 m for almost all natural surfaces. Measurement uncertainty ranges between +/-20 mm and +/0 60mm depending on output range. Operation temperature is -40 to +60°C.
