EC and pH Controllers
The first stand-alone units that provide continuous inline monitoring of the EC and pH of the irrigation solution. Units connect to an external alarm which will automatically sound if the EC or pH is outside of preset limits. Can be used to activate solenoid valves to dose fertilizer and/or acid to maintain the EC and pH within the desired range.
Screw calibration insures easy calibration and complete accuracy. Control boxes are made of moisture and chemical resistant housing. Electronic components are manufactured specifically to exact specifications. Designed to be used in harsh greenhouse and nursery environments. Require a 24 volt input (from a transformer).
