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 110WX model offers apparent wind speed and direction, air temperature, and barometric pressure readings. The WX Series WeatherStation® instruments meet a growing need for real-time, site-specific weather information. For moving applications where true and apparent wind are different, the 150WX is recommended and includes additional sensors such as a 10Hz GPS, solid-state compass, tilt sensors and a field replaceable relative humidity sensor.
