Total dissolved solids - Wikipedia

Total dissolved solids, (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form.TDS concentrations are often reported in parts per million (ppm). Water TDS concentrations can be determined using a digital meter.
