Model 3675 -pH Controller
Global Water"s pH Controllers are packaged in a 1/4 DIN panel mount controller box with dual SPDT Hi/Lo relays, manual set points and calibration potentiometers set into the front of the pH controller panel. The pH controllers feature an isolated 4-20 mA current output and an external pH/ORP select switch. The pH Controller"s display is a large 0.5 inch LCD screen. pH controller sensor connectors are a BNC input and spade lug screw type connector block. The pH Controllers require a Pt-100 ATC probe or a simulation resistor for temperature compensation.
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.
