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.
TDS Range: 0 – 990 ppm (mg/L) with a resolution of 1 ppm. From 1,000 to 9,9990, the resolution is 10ppm, indicated by blinking “x 10” symbol.
Power source: 2 LR44 batteries required. (included)
