KNF-407 extraction type coastal water quality monitoring station, automatic monitoring and sample keeping function, integrated extraction type water quality monitoring station main monitoring items are: PH, temperature, turbidity, conductivity, suspended matter, dissolved oxygen, COD, total phosphorus, TOC, chlorophyll, blue green algae, etc. KNF-407 Extraction water quality monitoring water station uses highly integrated technology to realize automatic water quality monitoring function in one cabinet. Compared with the traditional monitoring station house, it saves the trouble of land acquisition and station construction, significantly reduces the cost of station construction, easy deployment, low maintenance, suitable for river surface water, lake water
Product overview of KNF-407 surface water quality online monitoring system
KNF-4007 water quality online monitoring system is based on the requirements of Surface Water Environmental Quality Standard (GB3838-2002), which provides the basis and support for strengthening the safety management of water quality in water sources, and can also be used for monitoring rivers and sewage. Online and early warning is mainly carried out for the PH, conductivity, dissolved oxygen, turbidity, COD, ammonia nitrogen and temperature of water quality. The product adopts modular design, which is easy to install and maintain, and is suitable for the monitoring needs 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, 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 of surface water monitoring and analysis, data acquisition and transmission, equipment anti-control, monitoring and early warning, automatic sample retention, etc., which promotes the informationization and modernization of water management in water source areas and can comprehensively improve the management level.
