Whiteness and chromaticity tester TP-A10

Whiteness and chromaticity tester TP-A10 measures the whiteness, yellowness, color and color difference, reflectance value, stimulus value of the sample. It measures the paper opacity, transparency, light scattering coefficient, light absorption coefficient and ink absorption value. The compact, advanced circuit design ensures the accuracy and stability of measurement data. This color tester measures the ISO brightness (blue whiteness R457) & Z whiteness (Rz) of fluorescent whitening sample due to the emission of the fluorescent material.
