PHR-212 Industrial pH Controller/Recorder

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 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.
