TDS refers to the total amount of dissolved substances in water, including minerals, salts, metals, and other impurities. It gives us an indication of the overall quality of the water.
TDS meter is a great digital instrument to measure the amount of total dissolved solids (in ppm) in your water. It is important to know the TDS of your supply water as this number helps in determining the water purification technology you should use to get healthy and mineral rich water.
