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 ensure it delivers these results in every application.
The built-in temperature sensor is located close to the pH measuring glass, resulting in increased accuracy of temperature compensation and therefore the pH measurement. The integrated large Titanium liquid earth improves measurement stability by countering any stray or ground loop currents that can destroy the reference sensor.
