TDS TESTER

A TDS tester (Total Dissolved Solids tester) is a handheld electronic device used to measure the concentration of dissolved solids, such as minerals, salts, and metals, in a liquid—usually water. It provides a digital readout of the TDS level in parts per million (ppm), which helps assess water quality for drinking, aquariums, hydroponics, and industrial applications. TDS testers are simple to use and offer quick, accurate water quality assessments.
