120WX/120WXH weather station

Airmar 120WX/120WXH is a weather station whose main function is to provide information about weather changes. The structure is fixed, so the operation is more reliable. Installation is recommended for stationary objects.

Weather station 120WX/120WXH is a device in a compact package that combines many functions. It measures the apparent wind, its direction, ambient air temperature and atmospheric pressure.

Model 120WX comes with a heating element. Several features follow from this:

The station with a heating element can operate in harsh navigation conditions at temperatures as low as -40°C.

The operation of the heating element can be serviced both in automatic mode and directly by the user.

Stations with a heating element do not measure air humidity.

Mains supply 24 V.
