Drinking water source monitoring, surface water monitoring system -[KNF-400A] using sensor electrode monitoring scheme, no consumables and maintenance, low cost. Main monitoring parameters: pH, turbidity, temperature, conductivity, ammonia nitrogen, COD and other indicators, can be uploaded to Kainafo water quality testing platform through GPRS, and synchronously released to the LED screen.
Overview of KNF-400A series surface water quality monitoring system and water source quality monitoring system products：
KNF-400A-1 is an on-line water quality monitoring system based on the requirements of Environmental Quality Standard for Surface Water (GB3838-2002), which provides basis and support for strengthening the safety management of water quality in water sources. It is mainly used for online and early warning of turbidity, COD, PH, ammonia nitrogen, conductivity, oil in water and temperature of water quality. The product adopts modular design, is easy to install and maintain, and is suitable for single point and large area distribution. It is the first water quality online equipment for monitoring the discharged water.
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, and in view of the monitoring characteristics of drinking water, Kenafu Technology has a long-term, stable and effective solution. The system can realize the digital management of the whole process, such as monitoring and analysis of drinking water, data acquisition and transmission, equipment anti-control, monitoring and early warning, etc., which promotes the informationization and modernization of water management in water source areas and can comprehensively improve the management level.
