The OMEGA” PHCN-410
pH controller is a microprocessor-based
pH controller with automatic temperature compensation, a 4-digit
LED display, two SPDT mechanical relays, and a fixed 4-20
output.

We recommend that you bench-test all equipment prior to
installation. This requires wiring the equipment and checking relay
and output functions as well as
pH input (see section 2.2). This is
also a good time to initially calibrate the
pH electrode to the meter
(see section 3).

The 100 ohm Pt RTD temperature probe can be separate from

If an ATC input is not provided to the meter, the temperature
reading will default to 25°C. If the process temperature is constant,
but not 25”C, a precision resistor can be used to simulate the
appropriate temperature value to the unit. For example, if the
