The USH-9 is an ultrasonic sensor for the precise, continuous and non-contact recording of snow depths. The robust design, a special ultrasonic head as well as an extremely low energy consumption makes the USH-9 a very suitable system for extreme weather conditions and so for alpine and high alpine terrain.
