ORP Oxidation is a process in which a molecule or ion loses electrons. Reduction is a process by which electrons are gained. A measurement of the potential for these processes to occur is called ORP (Oxidation Reduction Potential). The ORP REDOX Potential Tester is a unique hand-held tester developed to determine this value. ORP is a result of the wide demand for an accurate, affordable ORP tester.

This instrument is particularly valuable because there are no chemical test kits or litmus paper that can measure this parameter. Until now the only alternative was an expensive ORP electrode used with a special pH meter with mV readings, now there is ORP. The high-tech platinum electrode assures accuracy along with fast response and excellent repeatability.
