OTT Pluvio² S - precipitation gauge

Compact universal weighing precipitation gauge

The professional rain gauge is a further development of the tried-and-tested OTT Pluvio², with state-of-the-art technology in a compact design that captures up to 400 mm of precipitation on a collecting area of 200 cm². It is virtually maintenance-free, fits onto 2-inch pedestals, needs little space and can replace conventional rain gauges or tipping buckets without any structural work

Parameters measured:
Cumulative precipitation, precipitation intensity, bucket content in real time and non real time Measurement technology:
Weighing principle Product Highlights:
Compact all-weather precipitation gauge for 2-inch pedestals, highly accurate, meets WMO requirements (Guidelines No. 8), nearly maintenance-free, lifetime calibrated
Interface: SDI-12, RS-485, impulse, status Request a quote or advice
  • Compact and relatively light precipitation gauge, with a weather resistant collecting bucket for 400 mm of precipitation (200 cm² collecting area)
  • Minimum space requirement - no problem to install on existing 50 cm x 50 cm concrete bases • any suitable vibration-free 2-inch pedestals can be used again
  • The intensity and cumulative data output fulfils the WMO directive No. 308
  • Highly-developed data capture and processing with signal analysis, filtration and noise reduction as well as algorithms that compensate for the influences of temperature and wind
  • Considerable measuring accuracy of ±1 mm, wide measuring range, and a high data accessibility of 99%
  • Output of high precipitation intensities of up to 3,000 mm/h without any time delay
  • Precise capture of the finest precipitation from as little as 0.03 mm of precipitation in an hour
  • Optionally available with adjustable ring heater – prevents the formation of ice or snow caps and keeps the orifice rim free • also deployable in solar operation in reduced voltage mode
  • Various output interfaces (SDI-12, RS-485, pulse/contact), configurable through USB by means of tablet PC or notebook
  • Low overall operation costs – lifelong calibrated ice-free, drift-free and virtually maintenance-free measuring device

The OTT Pluvio² S is designed for professional use, and is suited for automated and semi-automated measuring networks, especially in locations where only limited space is available.


  • Automated meteorological measuring networks
  • Weather observer measuring networks
  • Urban hydro-meteorological measuring networks
  • Precipitation stations for flood warnings and precipitation-runoff modelling
  • Precipitation stations as part of research projects
  • Weather radar systems for calibration and Z/R correlation
