By using the classical electrochemical principle, the measurement is reliable and the performance is stable. It is widely used in environmental protection water treatment, surface book, pure water, circulating water system, as well as electroplating, electronics, printing and dyeing, chemical, food, pharmaceutical and other manufacturing processes. In sewage treatment, drinking water treatment, surface water monitoring, pollution monitoring, industrial processes, such as the performance of excellence.
