A turn of a knob allows the applicator to adjust between 1/2 cwt/minute and 90 cwt/minute. A pump takes the chemical from the original container and mixes it with the supplied water. A second pump then boots the pressure, creating a fine spray particle to improve coverage. The Applicator also has a low-level alarm system with an auto start/stop switch that turns the applicator off and turns a red light on when the level in the chemical jug gets below 1 inch. Please call for more information.
