ORP Meters (Oxidation-Reduction Potential)

ORP – Oxidation-reduction potential measures the ability of a dam, lake, or river to cleanse itself or break down waste products, e.g. contaminants, and decaying plants or animals. When the ORP value is high, there is a lot of oxygen present in the water. This means that bacteria that decompose dead tissue and contaminants can work more efficiently. In general, the higher the ORP value, the healthier the lake or river is.
