In wastewater it distinguishes aerobic from anoxic and anaerobic conditions, so it is used to verify that nitrification, denitrification and sulfide control are working. In metal finishing it is the standard endpoint indicator for cyanide destruction and chromium reduction.\u003c\/p\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDrinking water and pool disinfection control\u003c\/li\u003e\n\u003cli\u003eWastewater treatment: aeration, denitrification and sulfide control\u003c\/li\u003e\n\u003cli\u003eCyanide destruction and hexavalent chromium reduction in metal finishing\u003c\/li\u003e\n\u003cli\u003eCooling tower and process water oxidant dosing\u003c\/li\u003e\n\u003cli\u003eRedox titrations and laboratory ORP measurement\u003c\/li\u003e\n\u003cli\u003eGroundwater redox characterization at contaminated sites\u003c\/li\u003e\n\u003cli\u003eAquaculture and hydroponics water quality monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eMaintenance note\u003c\/h3\u003e\n\u003cp\u003eA sluggish or non-responsive ORP electrode is usually a fouled platinum surface rather than a failed electrode.
