The World Health Organization (WHO) (1993) stipulates that the water used by residents must be in contact with a solution with a residual chlorine concentration greater than or equal to 0.5 mg per liter for at least half an hour in an environment with a pH value of less than 8.0. In life, water plants generally use residual chlorine analyzers, and the use of residual chlorine analyzers is mostly at the back end of water quality testing. Tap water is often disinfected with chlorine gas. Residual chlorine refers to chlorate plasma generated after chlorine gas is dissolved in water. These ions can be measured by residual chlorine analyzer, thus clearly understanding whether the water quality can be drunk after disinfection.
