Optimized for Steam Sterilization
The steam-sterilizable pH glass membrane of the InPro 3253 120/PT100 makes it optimal for processes where sterilization or autoclaving are required.
Low Maintenance for Your Operation
This pH sensor is designed for low maintenance pH measurements, from dirty industrial to hygienic and sterile environments.
Sterilizable and Autoclavable
This sensor provides fast and precise pH measurement, even after repeated autoclaving and sterilization cycles.
Material No.: 52002566
The InPro 3253 120/PT100 is designed to withstand the rigors of your production. Its pre-pressurized, maintenance-free reference system ensures high reproducibility and reliable measurement performance under diverse operating conditions.
The InPro 3253 120/PT100 is suited for chemical and biopharmaceutical production. Its certification covers hazardous zone use, biocompatibility of the electrolyte, and all relevant hygiene and safety regulations.
This sensor can measure pH in industrial processes and has a built-in PT100 temperature sensor. It is pressure resistant up to 4 barg (58 psig), has a watertight connector, and can withstand repeated sterilization and autoclave cycles.
