Maretron's outdoor weather station measures wind speed and direction, air temperature, barometric pressure, and relative humidity. The wind measurement is performed using ultrasonic sensors, which means there are no moving parts to wear out or to get caught in the rigging. The WSO100 accurately measures wind speed and direction under tilt of up to 30°, making it ideal for sail as well as power conditions. When used with the Maretron DSM200 display and SSC200 compass, the user will be able to view both apparent and true wind speed and direction as well as dew point and wind chill factor. |
