CONDUCTIVITY indicates the degree of ease with which current can flow through a solution and is represented by the reciprocal of specific resistance.

As SHOWN in the following figure, when pole plates of surface area A (cm2) oppose each other in the solution, the electric resistance Rc(Ω) is represented by Rc = r•L/A where r is specific resistance (Ω•cm), which indicates the degree of difficulty for current to flow depending on the solution.Conductivity Analyzer

When the conductivity is K (S/cm), K is determined by J/Rc. J is referred to as a cell constant and is a specific value which varies with the shape of the sensor, etc. In addition, if L and A are given because of J = L/A, the conductivity of K is derived by measuring the resistance Rc of the solution.

The unit of conductivity is S/m in SI units. The 1 S/m is EQUIVALENT to conductivity S between two electrodes each having an area of 1 m2 separated by a distance of 1 m. Because S/m value does not fit realistic FEELING, the conventional μS/cm value is used.Conductivity is also referred to as electrical conductivity or CONDUCTANCE.
