pH Sensor InPro3250i/SG/325

Name: pH Sensor InPro3250i/SG/325
Brand: Mettler Toledo

High Performance, High Accuracy pH & ORP.The InPro 3250i SG/325 is a digital, pre-pressurized, low maintenance ISM pH & ORP sensor combined with a temperature sensor for in-line measurement in demanding applications. The 325 mm version is optimal for medium to long installation lengths.

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.

Sensor Calibration & Maintenance Tools

iSense Adaptor Cable DS AK9-RJ12

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.
