Global Water's ORP Controller is a 1/8 DIN panel mount controller with dual SPDT Hi/Lo relays, manual set points and calibration potentiometers set into the front of the panel. The ORP controllers feature a voltage/recorder output and an internal ORP select switch. The ORP Controller's display is a large 0.56 inch high efficiency bright red LED. The ORP Controller's sensor connectors are a BNC input and spade lug screw type connector block. The ORP Controller requires a Pt-100 ATC probe or a simulation resistor for temperature.
The ORP controllers use an all solid state design to achieve low power consumption and reduced internal heating. Each ORP controller is heat cycled 100 hours before shipment. The ORP controller offers automatic pH temperature compensation from 0 to 100°C and set points that cover the entire ORP sensor span.
