Conductivity vs TDS

There is a strong and significant relationship between the conductivity and total dissolved solids content of the different sites.

Both of theses parameters are co-related as Conductivity measurement is able to conduct a quick estimation on the amount of the Dissolved Solids (DS).The TDS content of the waters had consisted of ions that contributed to the electrical conductivity of the waters. They mainly came from the various kinds of dissolved substances such as detergent, soap, oils and bacteria from hands and face.

Hence, from the graph, we find that as the content of total dissolved solids increases, the conductivity of the water increases as well.
