Airmar WS-300WX-RS422-IPX7 Ultrasonic Weather Station RS422 IPX7

The Airmar WS-300WX is a professional-grade ultrasonic weather station designed for marine, recreational, and commercial applications. Utilizing solid-state ultrasonic technology with no moving parts, the WS-300WX delivers highly accurate wind speed, wind direction, air temperature, barometric pressure, and humidity data in a compact, durable housing. This RS-422 output variant with IPX7 waterproof rating is engineered for reliable performance in demanding offshore and onshore environments.

Key Features:

• Ultrasonic Wind Measurement — No moving parts means zero mechanical wear and maintenance-free operation
• RS-422 Serial Output — Industry-standard serial interface compatible with a wide range of chartplotters, MFDs, and data loggers
• IPX7 Waterproof Rating — Fully sealed against water immersion, suitable for harsh marine environments
• Multi-Parameter Sensing — Simultaneously measures wind speed, wind direction, air temperature, barometric pressure, and relative humidity
• NMEA 0183 Protocol — Outputs standard NMEA 0183 sentences for broad compatibility with marine electronics
• Solid-State Design — Rugged construction with no moving parts ensures long-term reliability in saltwater and high-wind conditions
• Compact Form Factor — Low-profile design suitable for mast-top or rail mounting on vessels of all sizes
• Wide Temperature Operating Range — Engineered to perform in extreme cold and heat conditions

The WS-300WX integrates seamlessly with Garmin, Raymarine, Furuno, Simrad, and Humminbird chartplotters and multifunction displays that accept NMEA 0183 RS-422 input. Its ultrasonic transducer technology eliminates the cup and vane assemblies found in traditional anemometers, providing consistent accuracy without requiring recalibration or replacement parts over time.

Ideal for sailboats, powerboats, commercial vessels, weather monitoring stations, and meteorological research platforms, the Airmar WS-300WX-RS422-IPX7 represents a best-in-class solution for onboard environmental data acquisition.
