TDS stand for total dissolved solids, which includes salt, metal and mineral in the water. A TDS meter is an easy to use hand-held digital meter to instantly check your overall water quality. It allows you to stay on top of your drinking water quality at all times! With the push of a button, the TDS meter can tell you the water purity level, which will be displayed on the screen measured in parts per million (ppm). The lower the number showing on the TDS meter means the purer the water, with 0 ppm being perfect and pure water.
