What is ORP (Oxidation Reduction Potential)?
It is a value that shows the proportion of oxidizing ions (such as chloride ion) and reduction ions (such as calcium ion) in a substance that takes the form of solution. If this value is shown as a minus as compared with the reference value, this substance reduces other substances, and can easily be oxidized. If this value is shown as a plus compared with the reference value, the substance oxidizes others and it can be easily reduces. The unit is most often shown in mv (millivolt), and it is used as an index that shows the development of chemical reactions.
