Total Dissolved Solids(TDS) are the total amount of mobile charged ions, including salts or metals dissolved in a given volume of water. TDS, which is based on conductivity, is expressed in parts per million(ppm) or milligrams per liter(mg/L).TDS includes any inorganic element present other than the pure water molecule(H2O) and suspended solids. TDS: TDS includes a mixture of inorganic salts, mostly sodium, chloride, potassium, calcium, and magnesium.  Rather than testing the particular components, TDS is monitored by measuring the conductivity of the water with a digital meter. There is no test strip or color disk kit that can be used here, although at least one conductivity meter interfaces with a smartphone.
