  • Product Details

Overview of KNF-400D sewage well drainage end water quality monitoring products:

     KNF-400D sewage well drainage terminal monitoring system is composed of online digital sensor, wireless acquisition terminal and Kenafu water quality monitoring cloud platform monitor. The product is modular and the equipment is designed with low power consumption. Easy to use, simple to install, only 15 minutes to install, no need to break the road construction, direct shaft installation, no secondary pollution, low maintenance, good reliability, and can be laid on a large scale.Sensors can be selected from cleaning devices to cope with harsh environment. Users can match different kinds of sensors according to their own needs, such as water level, water temperature, COD, ammonia nitrogen turbidity, conductivity, dissolved oxygen, pH, oil in water, etc.
