Abstract
This invention consists in a device consisting of a vessel (1) containing chemical solution soluble in water, a sample room or sample itself (13), and electric conduction meter (3); and a method in which the chemical solution is brought into contact with the sample so as to absorb water adsorbed to the surface of the sample and then electric conductivity of the chemical solution is measured. By means of such a structure as above, water content having been adsorbed by the sample can be measured with high precision in a short, period of time.
