A TDS (Total Dissolved Solids) meter measures the concentration of dissolved solids in a liquid, typically in parts per million (ppm), which indicates the purity of water. An EC (Electrical Conductivity) meter measures the ability of water to conduct electricity, which correlates to the concentration of ions or conductive substances in the solution. Both meters are used to assess water quality, particularly in contexts like aquariums, hydroponics, and water purification systems.
