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” 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.
