Measuring pH and Redox (chlorine)

The pH and REDOX can also be measured by the SEKO company probes. Both probes can be connected simultaneously to one C-IT-0200I module, but with some risk of mutual influence of the two probes. It is necessary to verify, or find, the optimum placement of the two probes, to eliminate interaction.

Measurements performed in this way are only indicative and suitable for applications without high precision requirements.

Accurate measurements can be performed, e.g., by converters made by Mires, www.mires.cz.

The probes used in the example include: The Redox probe SRH-1-PT-S6, cable 6 m, and the pH probe SPH-1-S6, cable 6 m (produced by SEKO):
