IDEAL FOR HIGH FLOW RATES:
The GROmaster 100 injects one fertilizer stock solution directly into almost any sized pressurized water line. It works with flow rates from 10 to 5000 gallons per minute.
The high pressure stainless steel pump injects the concentrated fertilizer solution directly into the main water line. A mixing pipe is installed in the water line after the injection point, and the unit's EC probe is installed after the mixing pipe. A motorized ball valve on the unit is continuously adjusted to maintain the exact EC set point. The system can be started manually, but is normally started by a flow switch, making it fully automatic.
USER FRIENDLY:
The GROmaster 100 couldn't be easier to use. The control panel has only three knobs to set. One sets the exact EC desired; one sets stability (rate at which machine adjusts); and one sets the limits for the alarm function. The panel also has a digital readout that constantly displays the EC whenever the machine is functioning.
ALARM FUNCTION:
If the machine cannot achieve the desired EC set point in a reasonable time, the machine will turn itself off and emit an audible alarm. (Connections are also available for external alarms.)
