ORP Meter

ORP (oxidation reduction potential, also known as redox) measurement is used to indicate the presence of oxidizing or reducing conditions in water. This technology has gained recognition worldwide and is found to be a reliable indicator of bacteriological water quality. Some applications for ORP or redox measurement include chlorine testing, bleaching operations, estimation of bacteria kill times, or reduction of chromate wastes. For example: with a value of 600mV, the life of E.Coli in water is about 2 minutes; with a value of 700, the bacteria is killed in seconds. This handheld ORP meter is designed for the field, combining accurate electronics and a rugged, field-ready design.
