Airmar NMEA 0183 Marine Based WeatherStation (no Relative Humidity) w/Heater - WS-220WX-HTR

Model 44-856-1-01

  • Relative Humidity (RH) not available on heater models
  • Cables sold separately
  • Heater requires 24VDC


The Model 220WXH is Airmar’s solution for commercial fishing weather monitoring applications. Thermostatically controlled heating system for operation in ice-prone areas. Feature rich, in a durable, rugged, small footprint that is IPX4 or IPX6 rated; the model 220WXH calculates the theoretical wind speed and direction based upon the apparent wind, speed of the vessel, and vessel heading.

The Model 220WXH internal 10Hz GPS and three-axis electronic compass provide heading, position, speed over ground and course over ground functionality that is required for theoretical wind data processing and mobile applications. Equipped with a 3D compass with dynamic stabilization provided by the 3-axis rate gyro also enhances the rate of turn data.

  • Apparent and theoretical wind speed and direction
  • Thermostatically controlled heater element
  • Barometric pressure
  • Air and wind chill temperature
  • GPS position, speed over ground, course over ground
  • Three-axis solid-state compass with dynamic stabilization
  • Three-axis rate gyro – rate of turn
  • Three-axis accelerometer – best-in-class pitch & roll performance
  • Output: Via a single cable (various lengths available)
    • NMEA 0183/Serial protocol over RS-422 standard interface OR RS232 interface
    • NOTE: The 220WXH CANNOT be used with an NMEA2000® CAN bus network
