Extreme-Duty Confidence for Marine & Autonomous Systems
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.
