The water quality monitoring system is a system that integrates pipe network water quality monitoring sensors, data processing units, and internal water flows pipeline units. It can continuously measure temperature, PH, turbidity, and disinfectant indicators, and can extend water quality parameters such as conductivity and ORP. The disinfectant index adopts the DPD colorimetric method. The three disinfectant indexes of residual chlorine, total chlorine, and chlorine dioxide are optional. The cuvette has an automatic cleaning function, which greatly reduces the amount of maintenance and improves the stability of the measurement data. Need to purchase reagents locally. The turbidity adopts the 90 ° scattered light technology of EPA principle, adopts LED light source, low power consumption, and long life of the light source

  • Integrated design, save space
  • The internal wiring and waterway are highly integrated, and users only need to connect the power supply and enter and exit the water.
  • The internal waterway design can try to ensure that the water flow is stable during the internal measurement process of the equipment, and ensure the monitoring data is accurate;
  • DPD colorimetric analyzer, with automatic cleaning function, reducing maintenance
  • With a 7-inch color touch screen, the operation interface is simple, easy operation, reliable system, low maintenance
  • With data storage and curve display functions master the dynamic changes in water quality 
  • With automatic fault diagnosis function, abnormal information recording and uploading functions, such as parts failure, over-range alarm, over-standard alarm, and other information 
  • With three-level management authority 
  • Historical data download and curve display can intuitively and accurately understand and track the changes in water parameters within a certain period 
  • Optional wireless data transmission module.
