The value of ORP measurements has been popular since the 1960s as a way to gauge water quality. In 1971, the World Health Organization set a standard ORP value for drinking water disinfection at 650 ...

[Stephen]’s system uses commercially available sensors that track pH levels and Oxidation-Reduction Potential (ORP), both basic measurements that indicate water quality. A second set of sensors ...

Other- Any digital output other than the standard serial or parallel signals. Simple TTL logic signals are an example. The oxidation reduction potential instrument is available in several mounting ...
