Monitoring and control of redox potential in various industrial sectors:
• Effluent treatment management (chromic and cyanide)
• Monitoring drinking water systems
• Chlorine monitoring in swimming pools
• Monitoring dissolved oxygen in water
• Wastewater monitoring
• Measurement in deodorization towers

Redox potential is a key measure for assessing the balance between oxidizing and reducing components in a solution.
The redox electrodes presented here are combination electrodes, incorporating a measuring electrode (platinum or gold) and an Ag/AgCl reference electrode to guarantee reliable, stable measurement.

Reference system :
The Ag/AgCl system used in all our electrodes ensures optimum stability, with a ceramic or PTFE diaphragm as required.

Combined redox electrodes :
Measuring electrodes are available in two configurations.
• Platinum (dome-shaped): For standard applications such as swimming pools, dechromatation or wastewater.
• Pure gold (ring form): Specific to highly reducing environments such as decyanidation.
The metal part is in direct contact with the liquid and offers a design that facilitates cleaning while ensuring high reliability.

Installation :
To protect glass electrodes, they must be installed on suitable supports. The PG 13.5 threaded connection provides a solid, watertight hold. Several mounting options are available:
• Immersion mounting: For measurements in basins or tanks (doc 130-01, 135-01, 145-01).
• Circulation mounting: For measurements on piping (doc 140-01, 140-02, 141-01, 142-01).

Electrical connection :
To connect rH electrodes with coaxial connector, use a coaxial cable. These cables ensure low-loss signal transmission and protection against electromagnetic interference, essential for accurate rH measurements. We recommend 9060 or 9061 cables and 9054 connectors (see doc 160-01).

Care and maintenance :
To ensure reliable measurements, regular maintenance of REDOX electrodes is essential. Periodic calibration is also recommended to ensure measurement accuracy. If electrodes are not to be used for an extended period, store them in suitable conditions to optimize their life and preserve their performance.
