Manual

Catalog

WatchDog Sprayer Station is an all in one weather station that measures Wind Speed/Direction and Chill, Air Temperature, Barometric Pressure, Humidity and Dew Point. Mount directly on your equipment to monitor and log weather conditions on the go! The station uses an internal compass and GPS to adjust the wind sensor values by subtracting the vehicle speed and direction to compute the true values.
