Electrical Conductivity (EC) meters measure the capacity of ions in an aqueous solution to carry electrical current. The ranges in aqueous solutions are usually small so the basic units of measurements are milliSiemens/cm (mS/cm) and microSiemens/cm (µS/cm).
Conductivity is used world wide to determine the level of impurities in water supplies for domestic consumption and industrial use. Industries that employ this method include the chemical, semi-conductor, power generation, hospitals, textile, iron and steel, food and beverage, mining, electroplating, pulp and paper, petroleum and marine industries.
Some applications require the measurement of Total Dissolved Solids (TDS) in mg/L, parts per million (ppm) or parts per thousand (ppt). The TDS concentration can be obtained by multiplying the conductivity value with a factor which is empirically determined. The total TDS is a mass estimate and is dependent on the mix of chemical species as well as the concentration while Conductivity is only dependent on the concentration of chemical species.
