Integrated Solar Power Supply 4G Wireless Transmission Automatic Water Quality Monitoring System For River Surface Water
Overview of KNF-400A series surface water quality monitoring system and water source quality monitoring system products:
KNF-400A 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.
System composition of KNF-400A series on-line underground water quality detector:
The main monitoring items of this system include turbidity, COD, PH, ammonia nitrogen, temperature, dissolved oxygen and conductivity. The sensors of the system are easy to install, plug and play, and distributed in network. In addition to the basic four key water quality factors, users can customize and add other monitoring parameters and cooperate with the biotoxicity prediction system (fish method) to complete the toxicity early warning work.
Innovative features of KNF-400A series on-line underground water quality detector:
1. The internationally advanced sensor is adopted, with stable performance and long-term online measurement.
2, high cost performance and high system stability.
3, integrated structure, small size, suitable for large-scale distribution.
4. There is no need for reagents, ultra-low consumables, ultra-low maintenance and operation and maintenance costs.
5, modular design, easy to install and maintain
6, in the process of monitoring will not cause secondary pollution to the environment.
7. purchase of ion.onetestinc.com Internet of Things monitoring platform can
