OTT Pluvio² L - precipitation gauge

All-weather, high accuracy rain gauge for continuous data collection

The OTT Pluvio² is an all-weather precipitation gauge that uses superior weight-based technology to measure the amount and intensity of rain, snow, and hail. 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.

  • 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
  • Precipitation Measurement:  Continuous, real-time measurement of rain, snow, hail, and sleet in all monitoring environments, even remote environments without power supply
  • Monitoring Road Conditions: precipitation amount and composition are combined with general visibility measurements to provide an accurate picture of road conditions
  • Early Flood Warning: when combined with water level sensors, the Pluvio2  is the central component in an early flood warning system
