Airmar 300WX-IP67 Weather Station No Humidity - RS422 & CAN - White
The Airmar WeatherStation Instruments are unique, as they are the only weather monitoring system that can report Dynamic True and Apparent wind speed and direction/angle in one compact housing with no moving parts or external interfaces.
- Ultrasonic measurement of apparent and Dynamic true wind speed and direction
- Barometric pressure
- Air temperature and wind chill
- Calculated dew point and heat index
- GNSS position, speed over ground, and course over ground
- Three-axis, solid-state compass with dynamic stabilization
- Three-axis rate gyro supplies rate-of–turn data
- Three-axis accelerometer for best-in-class pitch and roll information
- Housing IP67 rated for dust/water-ingress protection
- Enhanced wind speed accuracy: 1.5 knots RMS at 20 knots
- Bluetooth wireless connectivity for use with Airmar’s CAST app to view data, configure sensors, and perform firmware updates
- Automatic baud rate detection for J1939 and ISOBUS (250 kbps / 500 kbps)

When equipment lives offshore, on deck, or in dusty environments, exposure is constant and failure is expensive.
The 300WX-IP67 delivers the same next-generation intelligence as the 300WX, but in a fully sealed, IP67-rated housing engineered for continuous exposure to water, dust, vibration, and harsh marine conditions.
This is the model trusted for offshore platforms, buoys, unmanned surface vehicles, commercial workboats, and long-duration autonomous deployments. It’s designed not just to perform — but to endure.
True Wind. True Awareness. Even at Sea - On moving vessels, apparent wind alone is misleading. The 300WX-IP67 continuously calculates Dynamic True wind by integrating GNSS speed data with stabilized heading and motion data to cancel out apparent wind and deliver the True wind speed and direction. That clarity improves navigation decisions, supports autonomous control systems, and enhances vessel performance optimization.
Built for Harsh Reality - The IP67 enclosure protects against water and dust intrusion, while the proven, rugged housing durability enhances long-term reliability in exposed environments. The 300WX-IP67 removes worry from the equation. It simply continues working — through spray, salt, vibration, and long deployments.
Seamless Connectivity Without Complexity - Like its counterpart, the IP67 model integrates easily into marine and industrial networks, including NMEA 2000, NMEA 0183, J1939, and ISOBUS systems. Bluetooth connectivity with Airmar's CAST enables remote configuration and firmware updates without removing it from its installed location, especially valuable for mast-mounted or difficult-to-access installations.
