<P>PROBLEM TO BE SOLVED: To provide a moisture measuring apparatus for moisture-containing material, in which easiness of measuring work can be improved and a measuring work time can be shortened, and a moisture measuring method. <P>SOLUTION: A moisture measuring apparatus 1 comprises a measuring probe 2 and an apparatus body 21 including a control circuit. In the measuring probe 2, an electrode body 4 and a temperature sensor 5 to be inserted into a measuring sample M are projected from a measuring probe body 3. The control circuit determines a dielectric constant or impedance of the measuring sample M on the basis of information on any one of a delay time of a reflection wave from the electrode body 4, a frequency of the reflection wave and a voltage of the reflection wave by applying a pulse signal to the electrode body 4 in accordance with a reflective measurement method and any one information item measured by the measuring probe 2, determines a moisture value of the measuring sample M on the basis of information on an analytical curve indicating a relationship between the dielectric constant and the moisture value or a relationship between the impedance and the moisture value stored and held beforehand, and also determines a moisture value after performing temperature compensation on the moisture value on the basis of the information on the temperature of the measuring sample M and the moisture value/temperature compensation information stored and held beforehand. <P>COPYRIGHT: (C)2013,JPO&INPIT |
