Properties and benefits
9 Registration of the snow parameters:
- Content of liquid water and ice
- Snow Density
- Snow water equivalent (SWE)*
9 Prediction of snowmelt of the snow pack
9 Recognition of increase of liquid water content in
snow pack at an early stage
9 Realistic representation of measured snow
parameteres
9 Simple and easy installation and set up
9 No calibration required
9 SDI-12 and RS-485 signal outputs
