The pH electrode S401 DIG and the ORP electrode S406 DIG are suitable for the measurement of pH and ORP in various applications.
The porous liquid junction resists fouling and chemical attack. The double junction of the reference electrode increases the operating life in applications containing sulphides (H2S) and metals such as lead, mercury and silver.
The new type of solid reference electrolyte allows a reference potential constant in time and at pressure and temperature variations.
The new capillary temperature sensor design places the Pt100 behind the (pH or ORP) sensitive membrane for accurate temperature compensation and measurement.The mechanical protection IP68 protects the high impedance signal of the electrodes from moisture that can be generated in immersion applications (condensation).
