Name: pH Sensor InPro3252i/SG/225
Brand: Mettler Toledo

Resistant to Hydrofluoric Acid

The InPro 3252i/SG/120 sensor has a prolonged lifetime in the presence of hydrofluoric acid due to its special HF-resistant 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.

Solution Ground Allows ORP Measurement

The InPro 3252i has a Pt-dot solution ground, eliminating the risk of electrostatic interference and enabling parallel pH and redox (ORP) measurement.

Reliable, Accurate and Robust

This pH & ORP sensor is designed to withstand the rigors of your production. Its pre-pressurized, maintenance-free reference system ensures high reproducibility and reliable measurement performance under diverse operating conditions.

Advanced Sensor Diagnostics with ISM

The InPro 3252i features a digital signal, plus intelligent diagnostics to help manage your maintenance. The sensor provides a clear display of its remaining lifetime, time remaining until calibration, and counts of the SIP and CIP cycles it has undergone.

Suitable for Hazardous Conditions

This pH and ORP sensor is ATEX and FM certified for hazardous areas.

Fast Replacement of Sensors

Ensure the safety of the maintenance team with the ability to Plug and Measure. The InPro 3252i can be calibrated away from the process using iSense software, and then quickly swapped into the process environment without the need to recalibrate.
