pH/ORP Transmitters

We supply two dependable industrial pH transmitters designed to meet the demands of a wide range of process environments. Whether you're building a modern, data-driven system or maintaining a trusted legacy setup, we offer both digital and analog solutions that ensure accuracy, reliability, and long-term performance in pH measurement. Both options are built for durability and precision in demanding industrial conditions.

The OCM44, our digital pH transmitter, is built for today's connected operations and features full support for Memosens™ technology, allowing easy sensor replacement, safer calibration outside the process, and seamless integration with a wide variety of manufacturers’ sensors. With advanced diagnostics, robust digital signal transmission, and true “plug and play” multiparameter sensor connectivity, the OCM44 is the smart choice for facilities prioritizing efficiency, data integrity, and long-term asset management.

For more traditional applications, our OPM2x3 analog pH transmitter remains a practical and trusted option. Available in either field or panel mount packaging, it can be used for standalone control and/or deliver a continuous, stable 4–20 mA signal for integration with standard PLCs and DCS systems. An extended firmware option with additional functionality is available with extended diagnostics, enhanced neutralization control, and automatic probe cleaning triggered by alarms and limits. Built for simplicity, durability, and compatibility, it is ideal for operations that value time-tested technology and straightforward maintenance.
