pH is the measure of the hydrogen ion concentration in a liquid. pH measures the acidity or alkalinity
of a liquid. The pH scale is logarithmic and runs from 0.0 to 14.0 with 7.0 being neutral. Readings less than 7.0 indicate acidic
solutions, while higher readings indicate alkaline or base solutions.
Chlorine and Ozone are the most common disinfectants used in the water
and waste water treatment industry. Oxidation-reduction potential (ORP) is the parameter
commonly used to measure REDOX reactions and is the only practical method we have to electronically monitor disinfectant effectiveness.
