Science At Your Fingertips

The PURAtest TDS Meter is a professional level water test meter that fits in your pocket! TDS testing is a great tool for drinking water, water filtration and purification, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, and more. A TDS meter typically displays the TDS in parts per million (PPM). For example, a TDS reading of 1 ppm would indicate there is 1 milligram of dissolved solids in each kilogram of water and 0 ppm being pure H2O. A TDS Meter indicates the Total Dissolved Solids (TDS) of a solution, i.e. the concentration of dissolved solids in it. Since dissolved ionized solids such as salts and minerals increase the conductivity of a solution, a TDS meter measures the conductivity of the solution and estimates the TDS from that.
