3675 pH CONTROLLER
pH controllers to monitor and control pH in process water or wastewater.
FEATURES:
- Automatic temperature compensation
- Dual ON/OFF relays
- Large LCD screen
- Front panel adjustment
pH Controllers Description
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.
