Brightness Meter--whiteness meter/tester is widely applied in paper and cardboard, pulp, cotton and fabric, plastic, ceramic and porcelain enamel, amylum, construction material, chemical industry, salt making and other testing department that need to test whiteness.
Function:
1. Test R457or ISO Brightness
2. Analysis if it contains fluorescent whitening agent and determination of reflection fluorescence produced by white fluorescent, that is, degree of whitening
3. Test the brightness value of Y10, that is, the green light diffuse reflectance factor Ry.
4. Test the non-transparency, transparency, light scattering and light absorption coefficient
5. Test the ink absorption value of paper and board.
Standards:
ISO2470: paper and board Blu-ray diffuse reflectance factor method (ISO brightness);
ISO2471: paper and cardboard is not transparent method;
ISO2469: d/o lighting observing geometry terms
