Product Description
TDS is the abbreviation for Total Dissolved Solids, which refers to the total amount of inorganic salts and organic matter dissolved in water. Its main components include calcium, magnesium, sodium, potassium ions, carbonate ions, bicarbonate ions, chloride ions, sulfate ions, nitrate ions, etc. A TDS meter is an instrument used to measure total dissolved solids. The unit of TDS is ppm (mg/L), and its reading is converted from conductivity at a ratio of roughly 0.7. The reference temperature for automatic temperature compensation of TDS meters is usually 25℃, with a temperature coefficient of 2% per ℃.
