The 120WX offers a truly best-in-class solution at a better price point than any other weather monitoring system on the market today.
Reliability and superior accuracy, along with no moving parts and plug and play installation, makes the 120WX an easy and affordable choice for any weather solution. The Airmar WX WeatherStation® instruments are unique, as they are the only weather monitoring system to offer true and apparent wind speed and direction in one compact housing—without the need for additional sensors. Ideal for stationary applications, the 120WX model offers apparent wind speed and direction, air temperature, and barometric pressure readings.
