EC Stands for Electrical Conductivity - which is the measurement of the ability of an aqueous solution to carry an electric current. It is measured with a small electrical current flowing between two probes set 1 centimeter apart. The EC as it is known, flows faster when a greater amount of salts are in the solution. Microprocessor technology scales the measurement of electro conductivity into either microSiemens or milliSiemens.
