The 220WXH is a heated weather station with ultrasonic wind sensors, GPS, compass, barometer, and accelerometer. Data output via NMEA 0183, no NMEA 2000 support Read more.
The AIRMAR 220WXH WeatherStation Instrument is a high-performance, solid-state marine weather sensor engineered for professional operations in cold climates and icing conditions. As part of the WX Series, it features solid-state wind measurement, full environmental sensors, GPS, electronic compass, and a 3-axis accelerometer, combined with an integrated heating system that prevents ice accumulation and ensures continuous operation in freezing environments. With no moving parts and enhanced thermal management, the 220WXH delivers stable, motion-corrected wind and weather data in extreme conditions.
This model is designed for vessels and platforms operating in polar regions, winter patrol environments, offshore installations, and high-latitudes where frost, snow, and ice can compromise conventional sensors. Suitable for commercial workboats, research vessels, patrol craft, and fixed stations, the 220WXH provides accurate true and apparent wind data, even during rapid vessel motion, while maintaining full functionality in temperatures well below freezing.
Solid-state wind measurement: Captures apparent wind speed and direction without moving parts.
Integrated heating system: Prevents ice, frost, and snow accumulation for reliable cold-weather operation.
True wind calculation: Combines GPS, compass, and motion data for stabilized true wind output.
3-axis accelerometer: Provides pitch, roll, and motion compensation.
Integrated GPS: Supplies position, speed over ground, and course data.
Electronic compass: Delivers accurate heading information for wind correction.
Environmental sensors: Measures air temperature, humidity, and barometric pressure.
Cold-climate design: Engineered for sub-zero performance with continuous thermal regulation.
No moving parts: Maintenance-free system ideal for long-duration deployment.

The 220WXH must be mounted in a clear, unobstructed location to ensure accurate wind, motion, and environmental measurements. An elevated mast position is recommended to reduce airflow distortion and prevent snow or ice interference. The heater power wiring and data cables must be routed using watertight grommets and marine-grade connectors. Proper integration with the vessel’s NMEA network is essential to maintain synchronized GPS, compass, motion-compensated wind outputs, and heater functionality.
