Automatic Online Digital Conductivity Controller for Sewage

Sewage treatment is an important part of environmental protection and is of great significance for ensuring the quality and ecological balance of water resources. In the sewage treatment process, conductivity is an important parameter to measure water quality, which reflects the content of dissolved salts in the water. Conductivity refers to the ability of a solution to conduct electricity, usually measured in μS/cm. The more ions the water contains, the higher its conductivity value. The conductivity of pure water is relatively low, and a 2-electrode stainless steel electrode can usually be used to accurately measure conductivity. For sewage, because the water quality contains various inorganic salts and organic matter, the conductivity value will increase. The conductivity range of sewage is usually 1500~2000μS/cm. The DUC2-EC digital conductivity controller developed and produced by Daruifuno can be used with the DEC790 conductivity sensor. The measurement range can reach…
