ORP / REDOX ELECTRODE ERS-2
ERS-2 electrode is designed for measuring oxidation-reduction potential (ORP, redox) in water solutions. It includes measuring half-cell in a shape of a spiral, platinum wire at the eletrode's end and silver/chloride reference half-cell with a constant potential. The electrode is equipped with a ceramic electrolytical junction. Its construction enables easy cleaning of the platinum electrode. The ERS-2 electrode is typically used in: controlling the process of the oxidation-reduction reactions in swimming pools, in the process of chemical and biological purification of industrial and domestic waste water, controlling the fermentation processes, etc. Examples: oxidation of cyanide with chlorine or hypochlorite and reduction of chomates to chromium ions in sewage created in galvanisation processes or surface metalworking. ERS-2 electrode is also useful in analytical laboratories as an indicator of an endpoint in titration in oxidation-reduction reactions (e.g. iodometry, bromatometry, permanganometry).
