ORP Electrodes

Oxidation-reduction potential (ORP) is an important indicator for measuring the redox capability of a solution and has wide applications in environmental disinfection, swimming pools, biomedical water treatment, pharmaceuticals, and petrochemical production. With increasingly refined control over production processes and higher environmental protection requirements across various industries, the need for real-time and accurate pH measurement has become an inevitable demand in the era of big data.
