InPro3100/150/PT1000pH Sensor
Features
- Reliable, Accurate and Robust – withstands the rigors of bioprocessing.
- Reliable When Cleaning is Needed – designed for in-line pH measurements where sensor cleaning and sterilization is required
- Versatile to Meet Your Application Needs – measures pH in challenging applications and has a built-in PT1000 temperature sensor.
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.
