An ORP (Oxidation-Reduction Potential) Meter is a scientific instrument used to measure the oxidation-reduction potential of a solution, which indicates the ability of a solution to either donate electrons (oxidize) or accept electrons (reduce). It is an essential tool in various fields such as chemistry, water treatment, biological processes, and environmental monitoring.
