AIRMAR 120WXH WeatherStation

The 120WXH has been carefully designed, with a highly effective thermostatically controlled heating system for operation in ice-prone areas, both onshore and offshore. The heater element is designed to keep the wind channel free of snow and ice.

Reliability and performance, along with no moving parts, makes the 120WXH the product of choice for operation in ice-prone areas.
