The Global Water’s pH Controller is a 1/4 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 controller features an isolated 4-20 mA
current output and an external pH/ORP select switch.
The pH Controller’s display is a large 0.5” LCD screen.
Sensor connectors are a BNC input and spade lug screw
type connector block. The pH Controller requires a Pt100 ATC probe or a simulation resistor for temperature.
The 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 isolated 4-20 mA current output
covers the input control range of 0 to 14 pH and 0 to 1400
mV. The pH Controllers DIN housing allows the
controllers to fit into standard panel cutouts, while
providing industrial weatherproof and environmental
housings.
