Demanding pH applications—particularly high-temperature, high-pressure and retractable installations—can push conventional analog sensors past their limits, introducing signal noise, wiring complexity and limited diagnostic insight. The Rosemount 350A High Performance pH/ORP Sensor is a digital pH/ORP sensor built to deliver reliable measurements in harsh processes while simplifying installation and maintenance.

The sensor converts and transmits pH/ORP data digitally, reducing susceptibility to electrical noise and helping teams reach a stable measurement faster. A digital Modbus interface paired with M12 quick-connect cabling supports plug-and-play commissioning and helps eliminate installation errors associated with manual wiring. The digital design also allows interoperability across Rosemount digital liquid analysis sensors, supporting simplified spares and standardization across sites.

The sensor stores calibration data and diagnostic information onboard, supporting bench calibration workflows and giving maintenance teams more context for troubleshooting. Captured sensor health indicators and event history support proactive maintenance planning and faster root-cause analysis.

Built for harsh applications, the sensor supports retractable mounting styles and is available with titanium body options and selectable reference electrolytes to match challenging process chemistries, helping maintain measurement performance where temperature, pressure, coating, or poisoning conditions can shorten sensor life.
