pH Sensor InPro3251/120/PT100
High Performance pH Measurement.The InPro 3251 120/PT100 is a pre-pressurized, liquid filled, low maintenance pH sensor combined with a PT100 temperature sensor for in-line measurement in demanding applications. The 120 mm version is optimal for short installation lengths.
Accurate at Cold Process Temperatures
The InPro 3251 120/PT100 provides stable and precise readings at temperatures down to -25⁰ C, thanks to its low temperature pH glass membrane.
Low Maintenance and Easy-to-Use
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.
