Name: pH Sensor InPro3100i/SG/425
Brand: Mettler Toledo

Rugged pH Sensor for Bioprocesses

The InPro 3100i offers stable measurement without risk of diaphragm clogging due to the patented Argenthal silver-ion trap reference system.

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.

Reliable, Accurate and Robust

The InPro 3100i SG/425 is designed to withstand the rigors of bioprocessing. It uses a gel-filled electrolyte, which requires less maintenance, and the silver-ion trap helps keep the junction clear, even in the presence of sulfide-bearing solutions.

Advanced Sensor Diagnostics with ISM

This pH sensor provides predictive diagnostics to help manage your maintenance. The sensor gives you a clear display of the remaining lifetime of the sensor, time remaining until calibration is needed, and counts of SIP and CIP cycles the sensor has undergone.

Reliable When Cleaning is Needed

The InPro 3100i is designed for in-line pH measurements where sensor cleaning and sterilization is required. The sensor can withstand in situ SIP and CIP processes while maintaining fast and precise measurements.

Versatile to Meet Your Application Needs

This sensor can measure both pH and ORP (redox), and has a built-in digital temperature sensor. It is pressure resistant up to 6 barg (87 psig) and has a watertight connector.
