The unit of measurement for conductivity is expressed in either microSiemens (uS/cm) or micromhos (umho/cm) which is the reciprocal of the unit of resistance, the ohm. The prefix micro means that it is measured in millionths of a mho. MicroSiemens and micromhos are equivalent units.
EC â Electrical Conductivity. Introduction. The electrical conductivity (EC) of a solution. is a measure of its ability to carry an electric. current; the more dissolved ionic solutes in a. water, the greater its electrical conductivity. Electrical conductivity (S) is the reciprocal of. electrical resistance (â¦): S =â¦â1.
