Gel-Filled Electrode for pH and ORP
The InPro 3100i SG/225 is a combined pH/ORP electrode and temperature sensor designed for measurement in bioprocesses where CIP and SIP procedures are required. The 225 mm version is optimal for medium installation lengths.
Rugged pH Sensor for Bioprocesses
The InPro 3100i SG/225 offers stable measurement without risk of diaphragm clogging due to the patented silver-ion trap in the 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.

Features and Benefits
Reliable, Accurate and Robust
The InPro 3100i SG/225 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 Where Cleaning Is Needed
The InPro 3100i SG/225 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.
