センサーSC25V
For pH measurement and control, stable, reliable, and accurate readings are essential. The SC25V pH sensor is engineered to deliver consistent, precise results in all applications.
The integrated temperature sensor is positioned near the pH measuring glass, enhancing temperature compensation accuracy and, consequently, pH measurement precision. The large titanium liquid earth minimizes interference from stray or ground loop currents that could compromise the reference sensor.
