pH Sensor InPro3250i/SG/120
High Performance, High Accuracy pH & ORP.The InPro 3250i SG/120 is a digital, pre-pressurized, low maintenance ISM pH & ORP sensor combined with a temperature sensor for in-line measurement in demanding applications. The 120 mm version is optimal for short installation lengths.
Highly Accurate in Extreme Conditions
The InPro 3250i SG/120 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 digital pH sensor has Intelligent Sensor Management (ISM) technology, offering predictive diagnostics to reduce maintenance and calibration.
Sterilizable and Autoclavable
This sensor provides fast and precise pH and ORP measurement, even after repeated autoclaving and sterilization cycles.
