These days, inexpensive conductivity meters are
available which can directly read the conductance or resistance of the
solution in the conductivity cell Once the cell constant and the resistance
of the solution in the cell is determined, the conductivity of the solution
is given by the equation:
cell constant

The conductivity of solutions of different electrolytes in the same
solvent and at a given temperature differs due to charge and size of the
