  • A useful comprehensive list of application is given in other literature along with appropriate S.U., filters, and applicable standard methods. Below, some of these applications are put into prospective, with only the most widespread and important ones mentioned.
  • Paper Industry - Our instrument is widely used to measure the “paper brightness” using S.U. “W”, which has a blue filter built in. gloss measurement using S.U. “P” and opacity measurement using S.U. “Y” with green tristimulus filter are also possible. For opacity the instrument is first set to read 100, with the sample placed on white plaque. Then a reading is taken with the sample on black surface this reading is % opacity.
