The SC25V is the our first combination pH sensor in a 12 mm design that includes an integral temperature element and a liquid earth electrode. This design provides a large electrolyte volume giving the sensor longer life than most comparable pH electrodes.

Having a stable, reliable and accurate measurement is of vital importance for pH measurement and control. The SC25V pH sensor has been developed and designed to make sure that this sensor will deliver these results in every application.

The build-in temperature sensor is located close to the pH measuring glass. This will result in an increased accuracy of the temperature compensation and therefore also the pH measurement. The integrated large Titanium liquid earth will improve the stability measurement countering any stray or ground loop currents that can destroy the reference sensor.
