<P>PROBLEM TO BE SOLVED: To provide a moisture percentage measuring method and a moisture measuring system that are capable of calculating a moisture percentage by precisely measuring the value of a current even if the current is a noisy output current. <P>SOLUTION: A moisture measuring method for calculating the water content of an analyte by using a moisture percentage measuring instrument 1 having at least a pair of a cathode and an anode fixed at an interval of 1 mm or shorter, immersing the cathode and the anode in the analyte, and then measuring the electrolytic current of water between the electrodes by applying predetermined alternate voltages to both the electrodes for each cycle includes steps of: applying alternating, rectangular-wave, or triangular-wave voltages to both the electrodes; taking out the output current value of a cyclic component based on the applied alternating voltage from a spectrum obtained by the frequency conversion of an output current-time output signal; and calculating the water content of the analyte from the output current value which is thus taken out. Moreover, the moisture measuring system includes a moisture measuring instrument 1, a measuring section 2 for measuring the electrolytic current of water; an analyzing section 3 for determining the water content, an output section 4, and a display section 5. <P>COPYRIGHT: (C)2010,JPO&INPIT |
