Abstract
The present disclosure relates to a method for measuring electrical conductivity and a system for measuring electrical conductivity using the same. The method includes obtaining a cell constant of a conductance cell using a conductivity standard solution, pouring a solution desired to be measured in the conductance cell, and applying predetermined direct current (DC) voltages to electrodes, disposed in the conductance cell, in a manner of changing the predetermined DC voltages in stages at each preset time (t), obtaining resistance of the solution, as a slope, from a linear relationship between the voltage and a peak current, measured for each voltage, and calculating electrical conductivity of the solution using the cell constant and the resistance of the solution.
