WatchDog Sprayer Station Description:

Product Manual

Reduce pesticide drift complaints...and monitor your current conditions Pesticide drift is increasingly important to commercial applicators. Now you can monitor wind speed and direction and data log weather conditions with the ultrasonic WatchDog® Sprayer Station. Accurate data helps pesticide applicators make important decisions regarding weather conditions that affect safety, drift, and proper pesticide application. User controlled data logging of weather conditions provides evidence of suitable conditions for pesticide application.

Smaller than a can of soda, this all-in-one weather station measures air temperature, humidity, dew point, wind chill, barometric pressure and apparent wind speed and direction

Station uses an internal compass and GPS to adjust the wind sensor values by subtracting the vehicle speed and direction to compute the true wind speed and direction

Field replaceable humidity sensor

Handles adverse conditions with a UV-stabilized, compact housing that is fully waterproof and resistant to chemicals

Reliability is enhanced by eliminating moving parts: the traditional wind vane and cups have been replaced with ultrasonic transducers

Continuously log your weather parameters at a user-selectable rate or hit the snapshot button to capture current conditions
