SNOW PACK ANALYSER SPA-2

RECORDING ALL IMPORTANT PARAMETERS OF THE SNOWPACK

The SPA-2 system records automatically and continuously all important parameters of the snowpack and allows, for example, predictions about the snow melting progress. The latest product generation, the SPA-2, now offers a completely new and much more user-friendly control interface, connecting analog sensors has become a lot easier and the new standard for data outputs is realized via a RS 485 or SDI-12 interface.
