1. Product information
Membrane residual chlorine/total residual chlorine/chlorine dioxide electrode is a composite digital electrode using membrane amperage method. The detection part adopts special permeable membrane technology, which has the characteristics of resisting chemical interference (mainly surfactants) and reducing pH dependence. The sensor is not limited by water quality conditions, and can be applied to tap water, swimming pool, medical wastewater, sewage treatment, industrial wastewater and other environments. The sensor has high response speed, stable working performance, low cost and less maintenance, providing users with reliable and accurate data.
