InPro3100i/SG/325pH Sensor
Features
- Reliable, Accurate and Robust. 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
- 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
Gel-Filled Electrode for pH and ORP.
The InPro 3100i is a digital ISM pH and ORP electrode with temperature sensor, designed for measurement in bioprocesses where CIP and SIP procedures are required. The 325 mm version is optimal for medium to long installation lengths.
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.
