  • Make measurement of ISO brightness (Blue Whiteness R457) and degree of whiteness for Fluorescent whitener.

  • Make measurement of CIE whiteness (Ganz whiteness W10 and Color cast value Tw10) Make measurement of whiteness of building materials and non-metallic minerals.

  • Make measurement of Hunter system Lab and Hunter (Lab) whiteness reflectance factor.

  • Make measurement of yellowness.

  • Make measurement of opacity, transparency, light scattering coefficient and light absorbing coefficient.

  • Make measurement of ink absorption.

Applications:

Paper, Board, Pulps, Chemical fiber, Textile, Plastic, Ceramic, Enamel, Salt, White cerement, Porcelain clay , washing powder and French chalk etc.

Standards:

ISO2470: paper and board Blu-ray diffuse reflectance factor method (ISO brightness);

ISO2471: paper and cardboard is not transparent method;
