150WXRS WeatherStation® Instrument for Rain Measurement and Environmental Monitoring

Airmar's WeatherStation WXRS delivers real-time data on rain intensity, accumulation, and duration. An acoustic sensor detects the energy of individual raindrops hitting the instrument’s top “umbrella.” This revolutionary rain-detecting sensor requires almost no maintenance. It has no moving parts or components that need to be emptied, cleaned, or become clogged with debris.

With little maintenance, a unique rain sensor, and a comprehensive suite of ultrasonic wind, temperature, barometric pressure, and relative humidity sensors, the WeatherStation 150WXRS has a much lower total cost of ownership than conventional measurement equipment.

Features

• Ultrasonic measurement of apparent wind speed and direction
• Acoustic measurement of rain accumulation, intensity, and duration
• Internal compass for wind-speed data referenced to magnetic north
• GPS for time stamping correcting for the variation between magnetic and true north
• Maintenance-free operation is superior to tipping buckets, weighing gauges, optical measurement. No obstruction and data integrity loss due to debris.
• Rugged, compact, UV stabilized housing with no moving parts
