SC29 Electrode for pH/Redox

Brand: Yokogawa Electric Corporation

This combined electrode can be used in processes with a constant pH value or for processes where the Redox potential is dependent on the pH in order to achieve a pH compensated Redox potential. 

In such a case a pH/Redox converter with a high input is required. All pH/Redox converters of Yokogawa have such an input.
