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. Supplied with one 30-day roll of recorder paper.
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, two 6 amp SSR. Accepts one pH electrode input through supplied pH transmitter.
PHCN-52 pH recorder and pH controller 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 30-day roll of recorder paper.
PHCN-53 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 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. Supplied with the PHCN-54 is one 30-day roll of recorder paper.
The battery powered PHCN-55 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 PHCN-55 accepts any pH electrode directly. Supplied with the PHCN-55 is one 30-day roll of recorder paper.
