pH Sensor InPro 3250i SG/225

pH Sensor InPro 3250i SG/225

High Performance, High Accuracy pH & ORP

The InPro 3250i SG/225 is a pre-pressurized, liquid filled, low maintenance pH & ORP sensor, combined with a temperature sensor, for in-line measurement in demanding applications. The 225 mm version is optimal for medium installation lengths.

Highly Accurate in Extreme Conditions
The InPro 3250i SG/225 provides stable and precise readings under extreme process conditions from pH 0-14 thanks to its high-alkali pH glass membrane.

Low Maintenance and Easy-to-Use
This pH sensor has Intelligent Sensor Management (ISM) technology, offering predictive diagnostics to reduce maintenance and simplify calibration.

Sterilizable and Autoclavable
This sensor provides fast and precise pH and ORP measurement, even after repeated autoclaving and sterilization cycles.
