Top 10 Online Residual Chlorine Meter Manufacturers in China 2026

Introduction to Residual Chlorine Meter

An online residual chlorine meter is a crucial instrument used to measure the amount of residual chlorine in water. Residual chlorine is an important parameter in water treatment, as it helps to ensure the safety and quality of drinking water, swimming pool water, and industrial process water. It can effectively disinfect water, killing harmful microorganisms such as bacteria and viruses. By accurately measuring residual chlorine levels, operators can adjust the chlorine dosage in a timely manner to maintain the appropriate disinfection effect and prevent over - or under - chlorination, which may lead to water quality problems or potential health risks.
