Replaced by Airmar WS-110WX
Airmar 120WX weather station for wind, temperature and barometer reading. It measures the speed and direction of the wind.
Reliable and highly accurate, the Airmar 120WX has no moving parts and is plug-and-play and its installation simplicity makes the 120WX an easy and affordable choice for any weather solution. The Airmar WX WeatherStation® instruments are unique in that they are the only weather monitoring system that provides true and apparent wind speed and direction in one compact housing, without the need for additional sensors. Ideal for stationary applications, the 120WX model provides apparent wind speed and direction, air temperature and barometric pressure measurements.
