Ideal for water and wastewater treatment, this pH/ORP controller measures -2.00 to 16.00 pH (or -1999 to 1999 mV ORP) with ±0.01 pH accuracy and automatic temperature compensation. It provides three 1 A SPST relays, a 0 to 20 mA/4 to 20 mA isolated output, and RS485 communications behind a blue-backlit 4-digit LCD. The NEMA 4X (IP65) enclosure panel mounts and includes built-in memory backup.

The PHCN-961/962 series of pH controller and transmitter provides a reliable method of monitoring and controlling pH in water treatment, electrolytic water cleaning, chemical industry, food process, cleaning water or wastewater treatment, and neutralization processes.
The controllers standard features include a digital display capable of displaying pH readings between -2 and 16 pH or ORP readings between -2000 an 2000 mV. Additional features include temperature, and status of relays, adjustable dual alarm set points, dead band adjustments of 0.01 to 2 pH of the setpoint, and menu-driven program to set up pH or ORP calibration.
The PHCN-961/962 is a basic pH or ORP controller, it includes a NEMA 4X (IP65) enclosure, digital display, two separate setpoints for high and low alarms, adjust dead bands, three 1 A SSRs. Accepts one pH or ORP electrode input through supplied pH transmitter.
