AI Overview BETA

The Lufft SHM 30 is a snow depth sensor that measures snow cover up to 10 m within seconds. Its opto-electronic method separates snow from grass, letting operators tell whether the measured surface is snow-covered. Weather services and road-surveillance teams can set programmable measuring intervals for snow monitoring in locations such as roads and winter sport areas.

Snow-depth accuracy: ±5 mm
Measuring accuracy: ±1 mm
Precision and reproducibility: 0.5 mm
Operating temperature: -40°C to +50°C
RS232 and analogue output interfaces
