PN-48AF Automatic Color Tester is used to measure the D65 brightness (R457), D65 fluorescence brightness, color and color difference, opacity/transparency, light scattering coefficient, light absorption coefficient and ink absorption value of objects. It is widely used in papermaking, printing, textile printing and dyeing, ceramic enamel, building materials, chemical industry, food, salt making and other industries.
It has the following features:
Measure the color and color difference reflected by the object, and can display or print: diffuse reflection factor Rx, Ry, Rz, tristimulus values X10, Y10, Z10, chromaticity coordinates x10, y10, z10; lightness index L*, chromaticity index a*, b*, chroma C_ab^*, hue angle hab, dominant wavelength λd, excitation purity Pe, color difference 〖?E〗_ab^*, lightness difference 〖?L〗^*, chroma difference ?C_ab^*, hue difference ?H_ab^*, Hunter lightness L and Hunter a, b, etc.;
Measuring D65 brightness (R457), can measure the fluorescent whitening degree produced by the excitation of fluorescent substances in samples containing fluorescent whitening agents (FWA);
Measure CIE whiteness;
Measure ceramic whiteness;
Measure Hunter whiteness WH;
Measure excitation purity Pe;
Measure yellowness index YI;
Measure whiteness of building materials and non-metallic mineral products;
Measure the opacity OP and transparency T of the sample;
Measure the light scattering coefficient S and light absorption coefficient K of the sample;
Measure the ink absorption value.
