PHCN-45

The PHCN-45 combines pH/ORP
measurement, recording and control in a
single compact unit. pH and millivolt
readings are displayed on a 6" mirrored
meter and the built-in chart recorder
provides a 30 day record. In the standard
mode, accuracy is ±0.1 pH and ±10 mV. If
increased accuracy is required, a 10x scale
expansion is provided. Easy to use front
panel controls can set both the high and low

limits for control to within 0.1 pH and to
activate a visual alarm when limits are
exceeded. If desired, an adjustable Time
Delay Safety Feature will shut off power to
the output if the pH does not return to the
control point within set time (0 to 30
minutes). This can prevent over addition of
neutralizing chemicals due to probe or
meter malfunction. A pulsed 5 Vdc alarm
output is available to drive a dc solid state
relay to indicate this condition.

PHCN-48

The PHCN-48 is similar to
the PHCN-47 with the
addition of a second
electrode input that allows
the user to connect one
electrode to the
meter/controller and the other
to the recorder so that
real-time monitoring of the
control system is possible. In
typical applications, the first
electrode is placed in the
input water flow where it
senses pH and activates the
control system. The second
electrode, located
downstream, drives the
recorder to provide a
continuous record of the pH
of the effluent from the
control system.

PHCN-47

The PHCN-47 is a single electrode input model that
combines the same functions as the PHCN-45 in a
NEMA 12 type cabinet that may be used in a harsh
environment.
