Years of experience in development and manufacturing of air pollution and precipitation samplers and the newest technology of electronic
controls guarantee a high quality product with a long lifetime and extraordinary reliability.


Automatic Precipitation Sampler for the collection and air-conditioned storage of rain and snow samples for later analyses.

The DIGITEL Wet-only sampler DRA-12 is characterised by the following features:


  • 32 polyethylen sampling bottles, 250 ml each or 12 polyethylen sampling bottles, 1000 ml each
  • automatic bottle change when bottles are full (capacitive sensor)
  • electronic registration of bottle number
  • lockable sampling chamber
  • motor-driven, precipitation-controlled funnel lid
  • motor-driven pivot arm
  • motor-driven bottle changer


  • programming by touch screen
  • manual control by touch screen possible
  • programmable time control for bottle exchange programs
  • response time of funnel lid closing to precipitation and precipitation end can be determined
  • programmable minimal sampling time per sample
  • logging of total sampling time per sample
  • logging of funnel lid opening times per sample
  • customer specific programs on request

Control electronics:
