Advantages

  • All sensors and display transmission units are integrated in a 620*430*300mm box. Highly integrated, reserved standard water inlet and outlet interfaces, on-site plug and play.
  • The internal structure is designed with a pressure regulating module and a flow stabilizing defoamer to ensure stable water flow at the sensor end Fixed, it is less affected by the pressure change from the pipe network.
  • The turbidity sensor has an independent steady flow defoamer and automatic blowdown equipment to ensure the accuracy of turbidity
  • The box is made of 304 stainless steel and sprayed to ensure good corrosion resistance and electromagnetic interference resistance.
  • The internal water part and the circuit part of the instrument are placed in their own independent chambers, and there are sealing strips, shielding strips and other processing methods between the chambers to ensure the separation of water and electricity, and the separation of dry and wet.
  • It has the functions of historical data record and query. It has the functions of power-off protection and automatic recovery of incoming calls, and the parameters set after power-off are not lost. It has the functions of automatic alarm and recording of abnormal data, such as ordering. The alarm can be displayed on the remote monitoring computer or sent to the mobile phone set by the user.
  • 7-inch touch screen and the all-Englishoperation interface are simple and clear, simple and easy to learn.
  • The modular design of the analysis instrument can easily realize the subsequent expansion of functions without major changes, which is convenient for customers to control the water information in all directions. (e.g. Additional information such as ORP, conductivity, water pressure, etc.).
