2.4. Accuracy
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.
