Pluvio 2

Developed in conjunction with industry-leading meteorological services, the OTT Pluvio²  employs a high-precision load cell and algorithms that compensate for wind, temperature, and evaporation, ensuring the highest accuracy precipitation measurements over time.

Parameters measured: Precipitation Intensity, cumulative, bucket content in real time and non real time
Measurement technology: Weighing principle
Product Highlights: All weather precipitation gauge without moving parts according WMO guide line No8
Interface: SDI-12 / RS-485, pulse

Features
  • Accurate measurement: precipitation accuracy within 0.004 inches with accumulation and intensity readings and filter algorithms to compensate for wind, temperature, and evaporation

  • Virtually maintenance-free operation: lifetime factory calibration, drift-free measurements, and robust protective housing eliminate field visits for instrument service
  • Multiple communication interfaces: SDI-12, RS-485, and Pulse Output options
  • Solar panel power options make the instrument ideal for remote locations
  • Easy software setup and a USB interface for communication with computer
  • Wind protection shield available for particularly exposed locations
  • Heated ring option available to prevent the accumulation of snow on the sensor
  • Easy installation onto 4" pipes
