<p>PURPOSE: To measure a plurality of performances of an object to be measured with one apparatus at the same time. CONSTITUTION: A separating means such as a rotating sector 5 separates the energy radiated from an object to be measured 3 into the respective wavelengths of the first measured wavelength, which is not absorbed into moisture, the second measured wavelength, which is absorbed into the moisture, and the third wavelength, which is absorbed into alcohol. A detecting element 6 can measures all the wavelength components, which are separated by the separating means. Operating means 91 and 92 measure the moisture percentage based on the ratio of a signal e2 corresponding to the second measured wavelength component and a signal e1 corresponding to the first measured wavelength component among the output signals of the detecting element and the other performances of alcohol, and the like based on the ratio of the signal corresponding to a third measured wavelength component e3 and the signal e1 corresponding to the first measured wavelength component. These parts are porvided.</p> |
