The CS725 measures snow-water equivalent (SWE) by passively detecting the change in naturally occurring electromagnetic energy from the ground after it passes through snow cover. It is mounted above the ground and has no contact with the snow. As the snow pack increases, the sensor detects the attenuation of the electromagnetic energy from the ground, and SWE can be calculated. The measurement area of the CS725 is 50 to 100 square meters (540 to 1,075 square feet), making it an excellent replacement sensor for the traditional snow pillow and snow scale.
The CS725 is powered using 12 Vdc and can either operate in a stand-alone mode, or be easily interfaced to a datalogger. With the addition of a wireless communication option, SWE values can be transmitted in real-time from remote sites.
None of our retired dataloggers are compatible.
