Total dissolved solids (TDS) are the total weight of all solids (minerals, salts, and metals) that are dissolved in a given volume of water, expressed in parts per million (PPM). The higher the TDS level, the greater the probability of harmful contaminants. Get accurate readings and learn more about your water quality and hardness with this Total Dissolved Solids Meter. This TDS meter measures water hardness in parts per million, ppm, by measuring electrical conductivity (ec).
