Featuring a rotary dial for easy information access, the Oregon Scientific WMR100 professional wireless weather station makes capturing weather data easier than ever! This unique weather station even includes a sensor pole for temp/humidity gauges that offers easy set-up! The WMR-100 measures a wide range of weather variables and allows you to add up to eight additional thermo-hygro sensors for extensive temperature and humidity monitoring. The unit comes complete with outdoor thermo-hygrometer, anemometer, and rain gauge, plus an indoor console with barometer, thermometer, and hygrometer.

The highly affordable WMR 100 weather station features an atomic clock that never needs resetting, indoor and outdoor temperature/humidity, wind speed and direction, rainfall range and rate, barometric pressure, dew point, wind chill, heat index, time and weather alarms, and much more! The attractive main display unit is powered by an AC adapter with battery backup.

Note: We do carry a magnetic compass to help you orient your anemometer to true north. For more information on set up, please visit the anemometer page on our WeatherShack education center.
