ORP (Oxidation-Reduction Potential) is a measure of oxidation capacity and reduction of the aqueous solution. Unlike a pH measurement that follows a logarithmic curve and therefore requires more calibration adjustments, O RP follows a linear relationship and does not need any instrument adjustments as well as electrode maintenance. ORP is a reliable method of measuring water quality and provides the operator with a unique measurement value.
