RS485 online digital conductivity sensor for sewage 

It is very important to measure the conductivity value of water quality. It can not only reflect the total dissolved solids in the water body, but also can be used in drinking water, industrial production, environmental monitoring and agricultural irrigation. Therefore, for the monitoring and control of water quality, the conductivity value is a parameter that must be paid attention to. Monitoring the conductivity value of sewage can provide information about the concentration of dissolved ions in sewage. Conductivity refers to the resistance encountered when an electric current passes through a conductor of unit length and cross-sectional area. Therefore, the higher the concentration of dissolved ions in sewage, the higher its conductivity will be. By monitoring the conductivity value of the wastewater, the ion concentration in the wastewater can be quickly and easily assessed. This assessment can help us determine the type and concentration…
