Whiteness Tester BSM-01 for the determination of the whiteness of the object, which is widely used in papermaking, textile, printing, plastics, ceramics, enamel, food, building materials, paints, chemicals, salt and other special body to be measured whiteness production and testing departments.

 >  APPLICATION PRODUCTS

      Paint, paper, aluminum foil, plastic

 >  FUNCTIONS

      * Determination of ISO whiteness (ISO Brightness, namely R457 whiteness), fluorescent whitening samples, 

         which can also be measured fluorescent whitening of the fluorescence emission substance produced.

       * Measured brightness stimulus value Y10.

       * Determination of opacity.

       * Determination of transparency.

       * Determination of light scattering and absorption coefficients.

       * Ink absorption value determination.
