Conductivity (EC)

What is Conductivity?

Conductivity is an expression of the ability of a solution to conduct electric current. It is expressed as a microsiemen (micro-Siemens per centimeter or µS/cm) or in higher conductivity levels as a millisiemen. It is also the reciprocal of resistivity.

Some industries such as water treatment have adopted a measurement expressed as TDS (Total Dissolved Solids). TDS is approximated with conductivity using a multiple factor and is expressed in parts per million (ppm).
