SPA - Snow Pack Analysing System

A world unique system for automatic and continuous measurement of all the relevant snow parameters including snow depth, snow density, snow water equivalent and contents of liquid water and ice

• Information above the whole snow cover
• Information above a specific snow depth level
• Information above an extended area, by measuring with up to 4 SPA- sensors
• No measurement errors caused by ice layers in the snow cover
• Simple and convenient installation even at hillsides
• Automatic, continuous measurement
• Energy-saving sensor operation

Applications

SSG - Snow Scale

For automatic measurement of the Snow Water Equivalent (SWE) to give a Realistic representation of actual snow

• High representatives of the measured value and minimisation of ice bridging effect
• High accuracy through optimised thermal flow between sensor and ground especially during the melting process
• 3 measuring ranges:
  - 0 to 200 mm SWE
  - 0 to 500 mm SWE
  - 0 to 1,000 mm SWE
• Resolution: 0.1 k/m² / 0.1 mm SWE
• Accuracy 0.2 %
• Measuring surface: 6.72 m²

USH-8 Ultrasonic Snow Depth Sensor

With its robust design this sensor is ideal for the reliable measurement of snow-depth in extreme conditions.

• Snow depth measurement range: 0 to 8 m
• Snow depth resolution: 1 mm
• Snow depth accuracy: 0.1 % (FS)
• Temperature measurement range: -35 °C to +60 °C
• Temperature resolution: 0.1 °C
• Temperature non-linearity: ≤0.15 %
