Liquid water content Liquid water content The presence of liquid water in the snowpack has a dramatic impact on its physical and mechanical behaviors. The measurement of this quantity provides very valuable information for many purposes, including avalanche forecasting, analysis of machine-made snow, and scientific studies related to snow metamorphism. Technical specifications Technical specifications • Liquid water content measurement range: 0-20 vol. % • Typical measurement uncertainty: 1 vol. % • Acquisition time: <1s • High accuracy thanks to a well-defined measurement volume • Robust stainless...
