PRECIPITATION SENSORS (1518 H3)

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
