Paper Brightness Spectrophotometer
Digital whiteness tester is used to determine the object's whiteness, yellowness, color and color difference, but also can determine the opacity, transparency, light scattering coefficient, light absorption coefficient and ink absorption value. The instrument is widely used in papermaking, printing, textile printing and dyeing, ceramic enamel, building materials, chemicals, food, salt and other industries, in line with GB7973: diffuse reflectance test (d / o) of paper pulp, paper and paperboard.
Test standards:
| ISO 2469 ISO12625-7 "Paper, board and pulp -- Determination of diffuse reflectance factor" |
| ISO 2470 "Paper and paperboard - Determination of whiteness (diffuse/vertical method)" |
| ISO 2471 "Paper and paperboard -- Determination of opacity (paper backing) -- Diffuse reflection method" |
| ISO 9416 "Paper - Determination of light scattering and light absorption coefficient (Kubelka-Munk)" |
Functions:
1. Determination of ISO whiteness (ie R457 whiteness), for fluorescent whitening samples, the fluorescent whitening degree generated by the emission of fluorescent substances can also be measured
2. Determination of lightness stimulus value
3. Determination of Opacity
4. Determination of transparency
5. Determination of light scattering coefficient and absorption coefficient
6. Measure the ink absorption value
