Name: pH Sensor InPro3100/UD/225/PT100
Brand: Mettler Toledo

Rugged pH Sensor for Bioprocesses

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

Can Be Installed Upside-Down

This sensor can be installed upside-down or at any desired angle, allowing access from the bottom of a tank or vessel without bubble interference.

Sterilizable and Autoclavable

This sensor provides fast and precise pH measurement even after repeated autoclaving and sterilization cycles.

Reliable, Accurate and Robust

The InPro 3100 UD/225/PT100 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.

For Bottom-Entry Installations

This sensor has a unique structure that allows 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 When Cleaning is Needed

The InPro 3100 UD/225/PT100 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.
