Product Overview 

 -------------------------------------------------- ------------------------------ 

 The ZB-A whiteness of color tester is the test objects whiteness, yellowness, color and color also can determine the paper opacity, transparency, light scattering coefficient, the optical absorption coefficient and the ink absorption value. Widely used in papermaking, printing, ceramics, chemicals, textile printing and dyeing, building materials, food, salt and other industries, 
 Instrument specific functions are as follows: 
 A measurement of body reflection color and color, can display or print: diffuse reflectance factor Rx, Ry, Rz, to stimulate the value of Y10, X10, Z10, chromaticity coordinates x10, y10, z10; the L * lightness, chroma a * b *, chroma C * ab, hue angle h * ab, dominant wavelength λd excited purity Pe, the color difference ΔE * ab, the lightness difference ΔL *, chroma difference, ΔC * ab, the hue difference (ΔH) * ab, Hunter system L, a, b. 
 (2) the measurement of ISO brightness (Blu-ray whiteness R457) and Z whiteness (Rz), can measure the fluorescent whitening sample fluorescence emitted by the fluorescent substance whitening degree. 
 Measurement of CIE whiteness (the Ganz white degree W10 and color cast value TW10). 
 (4) measurement of ceramic whiteness. 
 (5) to measure the whiteness of the building materials and non-metallic mineral products. 
 6. Measurement Hunter White degree WH. 
 7 measuring the degree of yellowness in YI. 
 Measurement sample opacity OP 
 Measurement sample transparency T 
 10 measurement sample light scattering coefficient S 
 11 measuring the sample optical absorption coefficient A 
 12 measuring ink absorption value.
