120WXH WeatherStation® Instrument
Part Number120WXH
NOTE: AIRMAR NO LONGER MANUFACTURERS THIS MODEL, PLEASE SEE WEATHERSTATION® INSTRUMENTS FOR AVAILABLE MODELS.
Heater for Ice-prone Areas
The 120WXH has been carefully designed with a highly effective, thermostatically controlled, heating system for operation in ice-prone areas—both onshore and offshore. The heater element keeps the wind channel free of snow and ice. Reliability and performance, along with no moving parts, makes the 120WXH the model of choice in cold climates.
- Ultrasonic measurement of apparent wind speed and direction
- Thermostatically controlled heater element
- Barometric pressure
- Air temperature
- Wind chill
- Housing rated IPX6 for water-ingress protection
- Data output via a single cable (various lengths available)
- NMEA 0183 serial data protocol over RS-422 standard interface or RS-232 interface
- NOTE: The 120WXH cannot be used with an NMEA 2000® CAN bus network.
