Mentor: S. Schnitt


The OTT Pluvio 2 is a precipitation gauge basing on a weighing measurement principle. It detects both liquid and solid precipitation by weighing the bucket content. The following values are recorded:

  • intensity
  • accumulated intensity
  • bucket filling level
  • temperature load cell
