The accuracy of ohmic system was compared and calibrated with the standard conductivity. The calibration results for
the accuracy of electrical conductivity of 0.1 M NaCl solution revealed that there was no significant difference between standard electrical conductivity of 0.1 M NaCl solution and the experiment data (maximum 4.3%). The electrodes were thoroughly rinsed using a brush and dematerialized with twice-distilled water after each run.
