Laser Snow Depth Sensor LSH-10

This laser-based snow depth sensor from SOMMER LSH-10 stands for unreached accuracy in measuring snow level.

The LSH use his millimeter-accuracy to output the very high resolution even over long measurement distances.

An optimized heating system used in the LSH enables the sensor to work in all weather conditions without any maintenance.

Opto-electronic/laser based rangefinder technology makes sure to provide the best measurement data possible.
