The 120WX delivers wind, temperature, and barometric pressure data for recreational boating. Ultrasonic, compact, and IPX6 rated with no moving parts. Read more.
The AIRMAR 120WX WeatherStation Instrument is a compact, solid-state environmental sensor designed to deliver reliable real-time data for marine and land-based applications. As part of the WX Series, it incorporates optimized electronics, solid-state temperature, humidity and barometric sensors, and a maintenance-free design with no moving parts. It provides consistent environmental measurements in dynamic conditions and integrates easily into monitoring or navigation systems.
This model is intended for vessels or platforms that require accurate readings of air temperature, barometric pressure, and humidity but do not need wind data. It is suitable for small commercial boats, utility craft, unattended monitoring stations, and fixed installations where environmental tracking is required without the complexity of wind measurement systems. Its compact footprint ensures simple installation while maintaining high measurement stability.

The 120WX should be mounted in a clear, unobstructed location to ensure accurate environmental readings. For marine use, placement away from exhaust flow, heat sources, and enclosed structures is recommended. Wiring must be routed using watertight grommets and marine-approved connectors to maintain system integrity. Integration with the vessel’s NMEA network or monitoring system should follow manufacturer specifications for correct power and data configuration.
