Whiteness and chromaticity tester LD-TP-A10

SKU: LD-TP-A10

Whiteness and chromaticity testerLD-TP-A10measures 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.Â 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.

✓ Stimulate D65 illuminator to illuminate
