Residual chlorine refers to the chloride added during the disinfection process, and the chlorine-containing substances remaining after killing bacteria. Residual chlorine value refers to the remaining residual chlorine content in water, which is an important indicator to measure the effect of water treatment. In general, the residual chlorine value in water should be controlled within a certain range, neither too high nor too low. Too high a residual chlorine value will have an impact on human health, and too low a residual chlorine value will lead to substandard water quality and cannot effectively kill bacteria. Residual chlorine controllers are mainly used in occasions where water needs to be disinfected, such as drinking water, swimming pools, water treatment plants, etc. In these occasions, the residual chlorine content in the water can be automatically controlled through the residual chlorine controller to ensure that the water quality is safe and up to standard. In addition, in some occasions where water needs to be stored for a long time, the residual chlorine controller can also be used to regularly disinfect the water to ensure the stability and safety of water quality. The ADS2-C3 chlorine controller of the daruifuno brand provides data display, transmission and control. Two SPST relays can be connected to equipment such as dosing pumps to control the residual chlorine value in the water.
