It is taken in by a calculation unit (not shown). In the calculation unit, the reflectivity and the transmissivity are calculated at a ratio with respect to 100% of the reflectivity and the transmissivity set at the time of calibration.

  The whiteness (polishing degree) is calculated from the reflectance and the transmittance. The degree of whiteness (polishing degree) can be calculated by obtaining a regression equation from data obtained on a trial basis. When the whiteness degree (polishing degree) of a new granular material D is 100%, wrinkles are attached. The whiteness (polishing degree) of the used granular material D1 can be obtained. The new granular material D is whitish, but if it is a used granular material D1 with wrinkles, it has a yellowish and dark color, and the used granular material D1 has a whiteness (polishing degree) of 80. % Or less.

  The whiteness (polishing degree) and the transmittance obtained in this way are displayed on the whiteness display unit 20 and the transmittance display unit 21 of the display unit 18 together with the number of measurements, respectively.
