HY-PURE Digital TDS Meter
To instantly check your overall water quality, TDS = Total Dissolved Solids, are the total amount of mobile charged ions, including salts or metals dissolved in a given volume of water. This pocket-size unit is also ideal for home or laboratory hydro-electrical conductivity testing.
TDS, which is based on conductivity, is expressed in parts per million (PPM) or milligrams per liter (mg/L). TSD includes any inorganic element present other than the pure water molecule (H2O) and suspended solids. TDS affects drinking water quality consumption. For drinking, the lower TDS level of the water, the better for your health.
