Designed for Upside-Down Installation
The InPro 3100i UD/120 is a combined pH electrode and temperature sensor that can be installed upside-down in bioprocesses where CIP and SIP procedures are required. The 120 mm version is optimal for short installation lengths.
Rugged pH Sensor for Bioprocesses
The InPro 3100i UD/120 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 easy calibration.
Sterilizable and Autoclavable
This sensor provides fast and precise pH measurement, even after repeated autoclaving and sterilization cycles.

Features and Benefits
Reliable, Accurate and Robust
The InPro 3100i UD/120 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.
Can Be Installed Upside-Down
This sensor has a unique structure allowing it to be installed upside-down or at any desired angle. This provides a solution for large vessels, double-jacket vessels and other installations where a standard top- or side-entry would be impossible.
Reliable Where Cleaning Is Needed
The InPro 3100i UD/120 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.
