The conductivity and TDS is about 1:2. TDS refers to total dissolved solids (English Total dissolved solids, abbreviated TDS), also known as total dissolved solids, the measurement unit is milligrams per liter (mg/L), which indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. The higher the TDS value, the more dissolved substances contained in the water. Total dissolved solids refers to the total amount of all solutes in water, including both inorganic and organic content. Generally, the conductivity value can be used to roughly understand the salt in the solution. In general, the higher the conductivity, the higher the salt, and the higher the TDS. In inorganic substances, in addition to ionic components, there may also be molecular inorganic substances. Since organic matter and molecular inorganic matter contained in natural water are generally not considered, the salt content is generally referred to as total dissolved solids.
