What does the ORP (Oxidation-Reduction Potential) value mean?
As the value measured with ORP meter is to show us the potential difference according to exchanging plus (+) electron and minus (-) electron, the measure unit is mV. On the basis of “O” mV which it reprsents the ORP value of hydrogen, plus value is judged to be strong oxidation power and minus value is judged to be strong antioxidant (reduction) power.
