PRECIPITATION SENSORS (1518 H3) Zurück send article to a friend print article
Precipitation sensors with weighing tipping bucket - measurement acc. to Joss-Tognini zum Niederschlagssensor 

A uniquely brilliant idea...

lies behind the weighing precipitation sensor (1518 H3).
Not only are collecting and drain funnel heated, but also the collecting ring. Here, the snow is thawed so that the snow fall is measured promptly.
The new electronically regulated three-circle heating device minimizes evaporation effects. Several thousand of these precipitaion sensors are in use world-wide.

   Suitable in high mountain areas
   Constant operating temperature 4°C +/- 1°C for accurate
     measurement
   2- or 4 cm³ high-quality stainless steel buckets
   Absolutely weather-proof
   Easy installation of the precipitation sensors
   Simple handling

Applications fields of these precipitation sensors are e. g.:
Meteorological reference device  automatic and high mountain area weather station  classical meteorology and hydrology  with lysimeters  sewage plants  building systems  water  management/agriculture  forestry
