Global Water's pH Controllers are precise instruments for the measurement and control of pH and mV (ORP).  Two output relays are provided on the pH Controllers for ON/OFF control.  The pH Controller's isolated 4-20 mA current output covers the input control range of 0 to 14 pH and 0 to 1400 mV.  The pH Controller's DIN housing allows each pH controller to fit into standard panel cutouts, while providing industrial weatherproof and environmental housings for your pH control system.
