Gel-Filled Electrode for pH.
The InPro 3100 is a pH electrode with temperature sensor, designed for measurement in bioprocesses where CIP and SIP procedures are required. The 150 mm version is optimal for short to medium installation lengths.
Rugged pH Sensor for Bioprocesses

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

Gel Electrolyte Reduces Maintenance

This is a gel-filled electrode that provides effective, accurate pH measurement with low maintenance requirements.

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 150/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.

Reliable When Cleaning is Needed

The InPro 3100 150/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.

Versatile to Meet Your Application Needs

This sensor can measure pH in challenging applications and has a built-in Pt100 temperature sensor. It is pressure resistant up to 6 barg (87 psig) and has a watertight connector.
