METHOD FOR MEASURING ELECTRIC CONDUCTIVITY AND ELECTRIC CONDUCTIVITY MEASURING SYSTEM USING THE SAME

摘要

The present invention provides a method for measuring electric conductivity and an electric conductivity measuring system using the same. The method comprises a step for calculating a cell constant of a conductance cell by using a standard solution; a step for changing a specific direct current voltage at a predetermined interval of time (t) by stages by putting the solution to be measured into the conductance cell; a step for obtaining the resistance value of the solution, which is a slope from linear relationship of the voltage with a peak current by using the peak current measured at voltages; and a step for determining the electrical conductivity of the solution by using the cell constant and the resistance value of the solution.
