Oxidation is the process by which a molecule or ion loses electrons. This happens most easily in water treatment, swimming pools and spas where oxidizers, such as chlorine, are added to water to destroy contaminants. The higher the ORP value, the greater the sanitizing power of your water. ORP testers can provide valuable indications about water quality and alkali levels. HI 98201 is a unique handheld tester developed for quick and inexpensive tests. The HANNA ORP meter tester instrument uses a unique platinum electrode which can be pulled out when a blockage occurs
