Omega StrongSame Quality Product – New Name!
We’re building a stronger, unified brand so we can provide you with the best products in the industry. To do this, the Newport branded products will now be Omega branded starting Nov 26, 2018. You can expect the same support and quality as always, and of course the same features and specs, just with a new part number and logo. Please refer to PHCN-37 products at for details.

This microprocessor-based 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 INFCPH can be interfaced with a variety of pH electrodes.

The INFCOR and INFCOP series have been discontinued. Please contact our Sales Engineering department if you are in need of a replacement for these series.
