OTT Pluvio2

All-season rain gauge

Part # pluvio2

ott pluvio

Recognized worldwide for its precision and performance, the OTT Pluvio² is an all-weather precipitation gauge that uses superior weight-based technology to measure rainfall, snow or hail.

The Pluvio² determines the collection bucket weight every 6 seconds. The difference between this measurement and the known weight of an empty collection bucket equals the precipitation accumulation. The difference between the current bucket content and the previous measurement equals precipitation intensity.

The OTT Pluvio² evaluates each measurement and compensates for external influences such as temperature, wind, and evaporation.

  • Large collection capacity—750 mm or 1500 mm
  • Accurately measures wide range of precipitation intensities
  • Real-time intensity measurements (in/min or in/hr)
  • Accumulation measurements with consistent 5-minute delay
  • Automatic, continuous measurement
  • Drift-free, hermetically sealed measuring platform
  • Complies with WMO guideline no. 8
  • USB interface for communication with a computer
  • Pluvio² software for basic setup and control measurements
  • 4” flange for easy installation
  • Optional ring heater for use in cold climates (1500 mm version only)

What's the Easiest and Quickest Way to Start Collecting Data and Access it Anywhere?

The Answer's in the Cloud.

eTracker is a cellular modem and "virtual" cloud-based data logger in one (meaning you don't need to install a separate data logger). Simply connect your sensor and a power source to eTracker and you're done. Configure (or reconfigure) anytime from any Internet-connected device, and use Stevens-Connect to retrieve your data, or forward it to your favorite software system.
