What does ORP mean in practice?
The result in millivolts is the result of all oxidants and reducers and pH, therefore it is not clearly converted into the chlorine concentration.
When does it matter?
ORP tracks changes in process conditions well, but does not independently confirm a specific disinfection dose.
Which solutions are related to it?
The value is compared at the same point and pH range, while simultaneously measuring the actual oxidant using a selective method.
