Highly Accurate in Extreme Conditions
The InPro 3250i SG/325 provides stable and precise readings under extreme process conditions from pH 0-14 thanks to its high-alkali pH glass membrane.
Low Maintenance and Easy-to-Use
This digital pH sensor has Intelligent Sensor Management (ISM) technology, offering predictive diagnostics to reduce maintenance and calibration.
Sterilizable and Autoclavable
This sensor provides fast and precise pH and ORP measurement, even after repeated autoclaving and sterilization cycles.

Reliable, Accurate and Robust
The InPro 3250i SG/325 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.
Advanced Sensor Diagnostics with ISM
This pH sensor features a digital signal and intelligent diagnostics to help manage your maintenance. The sensor provides a clear display of its remaining lifetime, time remaining until calibration, and counts of the SIP and CIP cycles it has undergone.
The InPro 3250i SG/325 is suited for chemical and pharmaceutical production. Its certification covers hazardous zone use, biocompatibility of the electrolyte, and all relevant hygiene and safety regulations.
Versatile to Meet Your Application Needs
This sensor can measure both pH and ORP (Redox), and has a built-in digital temperature sensor. It is pressure resistant up to 4 barg (58 psig), has a watertight connector, and can withstand repeated sterilization and autoclave cycles.
The DS AK9-RJ12 is a USB cable adaptor for connecting ISM 1-wire sensors to iSense software. This allows pH, DO and CO2 sensors to be evaluated, maintained and calibrated in the workshop or laboratory.
Diagnostics Away From the Transmitter
The iLink module allows you to access all of the diagnostics of your ISM sensors away from the process with iSense desktop software.
Application Profiling Drives Performance
Store application data on iSense and load directly into an ISM sensor. This allows sensors to learn from preceding sensors in the same process.
Easy Access to Paper Free Documentation
The iLink cable allows sensor calibration and adjustment protocols to be generated automatically in iSense and stored in a fully digital database.
