  1. 1.product overview of KNF-400 tap water quality online detector system:

  2. KNF-400 on-line monitoring system for factory water quality is based on the relevant requirements of Hygienic Standard for Drinking Water, which provides the basis and support for strengthening the safety management of drinking water. It mainly carries out on-line and early warning for turbidity, residual chlorine, PH, temperature and TDS of water quality. The products are modular in design, easy to install and maintain, and can also be equipped with monitoring indicators such as dissolved oxygen, conductivity and ORP. It is suitable for the monitoring requirements of single point and large area distribution. At the same time, based on the research and development, production and operation experience in water quality online terminal monitoring equipment, data acquisition and transmission, environmental monitoring and management system, it can realize the digital management of the whole process of drinking water monitoring and analysis, data acquisition and transmission, equipment anti- control, monitoring and early warning, and promote the informationization and modernization of drinking water management, which can comprehensively improve the managemen
