The PHR-212 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 PHR-212 series includes a digital display,
digital switches for alarms set points, 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 set points, dead band
adjustments from 1 to 50% of set point, 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. PHR-212 pH recorder includes a
digital display, enclosed in a NEMA 4X enclosure and accepts pH
electrodes directly. Supplied with one 30-day roll of recorder
paper. PHC-212 is a basic pH controller, it includes a NEMA
4X enclosure, digital display, two set points for high and low alarm,
adjustable dead band, two 6 amp SSR. Accepts one pH electrode input
through supplied pH transmitter.
PRC-212 pH recorder
and pH controller combines the features of the PHR-212 and PHC-212
into one compact unit. It accepts one electrode through the
transmitter that drives the recorder, controller and digital
display. Supplied with the PRC-212 is one 30-day roll of recorder
paper. PRCD-212 pH recorder/controller 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 PRCD-212
is one 30-day roll of recorder paper.
PRCD-212 is supplied
complete with rugged NEMA-4X case,
pH transmitter and
pocket thermometer.
Electrodes purchased
separately.
PHCD-212 is a versatile
dual pH controller. The PHCD-212 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.
The battery-powered BPR-212 pH recorder (not
shown) is perfect for use in hostile environments and remote
locations, the battery powered recorder is enclosed in a NEMA 4X
enclosure. It uses a 6V rechargeable battery that may be left
unattended for approximately 2 weeks. The BPR-212 accepts any pH
electrode directly. Supplied with the BPR-212 is one 30-day roll of
recorder paper. The BPR is available with range of 2-12 or
0-14.
