Accurate Snow Depth Measurement with Advanced Laser Technology
The SOMMER LSH-10 laser-based snow depth sensor delivers unmatched precision in measuring snow levels. Its millimeter-accurate readings ensure exceptionally high resolution, even over long distances. With an optimized heating system, the LSH-10 operates reliably in all weather conditions, requiring no maintenance. The use of opto-electronic laser rangefinder technology ensures the highest quality measurement data.
Applications
The LSH-10 thrives in extreme environments, such as Antarctic research stations or high-altitude mountain regions. Built for durability, it provides consistent, maintenance-free measurements in temperatures ranging from -40Β°C to 50Β°C. Its high-energy laser pulses handle challenging reflection conditions, including powder or fresh snow.
Performance in the Field
Thanks to its powerful laser technology, the sensor delivers accurate results even in the most challenging conditions. It is highly reliable, energy-efficient, and user-friendly, making it ideal for field deployment. Operating temperatures as low as -10Β°C are possible without heating, while smart heating minimizes energy use to warm the laser module and front screens only when necessary.
