Description
AIRMAR 220WX WeatherStation; Instrument
Available Models: 120WX, 220WX From racing and cruising sailboats to yachting and commercial fishing, Airmar has WeatherStation; products specifically designed for your marine application. The WX Series WeatherStation instruments meet a growing need for real-time, site-specific weather information. For applications where theoretical and apparent wind are important, the 220WX is recommended and includes a 10Hz GPS, three-axis solid-state compass, rate gyro and tilt sensors. This model features configurable NMEA 0183 and NMEA2000; digital data outputs, providing unparalleled versatility for all your weather monitoring needs. Both models offer a truly best-in-class solution at a better price point than any other weather monitoring system on the market today.
Features
The Model 220WX is Airmar’s solution for commercial fishing weather monitoring applications. Feature rich, in a Durable, Rugged, Small footprint that is IPX4 or IPX6 rated; the model 220WX calculates the theoretical wind speed and direction based upon the apparent wind, speed of the vessel, and vessel heading.
The Model 220WX internal 10Hz GPS and three-axis electronic compass provide heading, position, speed over ground and course over ground functionality that is required for theoretical wind data processing and mobile applications. A 3D compass with dynamic stabilization provided by the 3-axis rate gyro also enhances the rate of turn data.

*When the wind speed is less than 2 m/s (4. 6 MPH) and/or air temperature is below 0°C (32°F),
wind, temperature, and relative humidity readings will be less accurate. 
**Wet conditions include moisture, rain, frost, dew, snow, ice and/or sea spray in the wind channel. 
***Temperature and relative humidity reports invalid during heater operation.
