⻬ Includes Two Wire 4 to 20 mA Transmitter
⻬ Optional ORP Controller
The PHCN-50 Series of pH recorders and controllers provides a
reliable method of monitoring, controlling and recording pH levels
of various industrial and chemical processes. Featuring an
extensive list of standard features, the PHCN-50 series includes a
digital display, digital switches for alarms setpoints, remote mount
pH 4 to 20 mA transmitter, 6 amp solid state relays, front panel
adjustable dead band pots and NEMA-4X enclosure.
The controllers standard features include a digital display capable
of displaying pH readings between 2 and 12 pH, adjustable dual
alarm setpoints, dead band adjustments from 1 to 50% of
setpoint, programmable time safety delay which activates when
pH correction time is excessive and a stand by switch that
disables the controller functions during calibration.
The recorder utilizes inkless pressure sensitive recording paper for
30 days of recording and front panel mounted calibration
adjustments.
PHCN-50 pH recorder includes a digital display, enclosed in a
NEMA 4X enclosure and accepts pH electrodes directly. Each unit
is supplied with one 30-day roll of recorder paper.

PHE-6510 electrode, $134 and PHEH-65-10
assembly with ATC, $55, shown smaller than
actual size, see page D-32.
PHCN-51 is a basic pH controller, it includes a NEMA-4X
enclosure, digital display, two setpoints for high and low alarm,
adjustable dead band, and two 6 amp SSRs. It accepts one pH
electrode input through the supplied pH transmitter.
PHCN-52 pH controller/recorder combines the features of the
PHCN-50 and PHCN-51 into one compact unit. It accepts one
electrode through the transmitter, that drives the recorder,
controller and digital display. Supplied with the PHCN-52 is one 30day roll of recorder paper.
PHCN-53 pH controller/recorder uses two independent pH probes
in a wall mounted NEMA-4X enclosure. Each pH electrode
performs a separate function. The electrode input from the
supplied pH transmitter drives the digital display and controller; the
second pH electrode drives the recorder directly. The recorder
electrode may be placed downstream from the control point to
record the adjusted values. Supplied with the PHCN-53 is one
30-day roll of recorder paper.
PHCN-54 is a versatile dual pH controller. The PHCN-54 accepts
two separate electrode inputs and can adjust pH at two separate
locations. The dual pH model is supplied with two 4 to 20 mA pH
transmitters. When one of the two controllers is configured with
the optional ORP controller, it may be used for cyanide destruction
or chrome reduction.
