PROBLEM TO BE SOLVED: To provide a method and device for accurately measuring the concentration of CaCO3 in a slurry in a short time even if the concentration of CaCO3 in the slurry fluctuates abruptly. SOLUTION: In this measuring method, the flow of a slurry flowing in a measuring cell 8 is varied depending on the amount of fluctuation per unit time of the detected value of the concentration of dissolved CO2 in a slurry as measured by a dissolved CO2 meter 9. Preferably, when the amount of fluctuation per unit time of the value detected by the dissolved CO2 meter 9 is equal to or greater than a certain value, the flow of the slurry flowing in the cell is increased for a certain time and then returned to its initial value. |
