Airmar WeatherStations®

As of January 2016 Airmar has restructured the WeatherStation range to simplify ordering. These new models are designed specifically for marine use. The WS-120WX and WS-220WX do not include humidity as standard. Instead, an optional add-on humidity sensor is available to field-upgrade either of them, or as a kit when you purchase one of these new sensors. Adding humidity sensing is a simple plug-and-play two-screw installation and can be completed at any time by any skill level. A heater option will also be available in Spring 2016, resulting in a total of six assembly numbers available for the recreational industry.

  • WS-120WX : No humidity
  • WS-120WX-RH : Kitted with humidity sensor
  • WS-120WX-HTR : Heater but no humidity sensor
  • WS-220WX : No humidity
  • WS-220WX-RH : Kitted with humidity sensor
  • WS-220WX-HTR : Heater but no humidity sensor

The WS-120WX and WS-220WX and the variants listed above are the only models that Gemeco will have available in the future.
