The Global Water’s pH/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 pH/OPR controller features a
voltage/recorder output and an internal pH/ORP select
switch. The display is a large 0.56” high efficiency bright
red LED. Sensor connectors are a BNC input and spade
lug screw type connector block. The pH/ORP Controller
requires a Pt-100 ATC probe or a simulation resistor for
temperature.
The pH/ORP controller uses an all solid design to
achieve low power consumption and reduced internal
heating. Each controller is heat cycled 100 hours before
shipment. The controller offers automatic pH temperature
compensation from 0 to 100oC and set points that cover
the entire sensor span.
