This microprocessor-based family of pH panel mounted controller is designed for a wide variety of environmental monitoring applications. The units features automatic or manual temperature compensation of pH, two 5 amp mechanical relays and a choice of a scalable 4 to 20 mA, or 0 to 20 mA control or recording output or a 0 to 10 V output. For ease of operation all calibration and parameter setpoints are selectable through the front keypad.The PHCN model can be interfaced with a variety of pH electrodes.
*The ORCN and OPCN models have been discontinued. Please contact our Electronic Engineering department if you are in need of a replacement for these series.*

pH controlerThe instruction book is very terse, but the device works very well.

Small, compact and accurate.I have a variety of Omega pH meters at my company. The quality is excellent. I have never been impressed with technical support though, at least in the pH meter area. The only downfall I see to this product is that there is not a dedicated, selectable option for one of the output relays for a failed pH probe like other, more expensive pH meters have.
Hi, My Name is Dee, our PH Controller is reading .8 lower than it should be. Do you have a document that shows how to re-calibrate our PH Controller Item# PHCN-37?
