YT-ACM Automatic computer color meter is the professional instrument to test the object of the whiteness, yellowness, chromatic aberration, opacity, transparency, light scattering coefficient, optical absorption coefficient, and ink absorption value. It is widely applied in paper, cardboard textile, painting, chemical building materials, plastic, cement, food salt, ceramics cosmetic etc.
The specific is the following:
● Measure the color of object , report diffuse reflectance factor Rx, Ry, Rz ● Stimulus value X10, Y10, Z10;chromaticity coordinate x10, y10, z10 ● Lightness L*;chrominance a*, b*;chromaticity C*ab; hue angle h*ab; dominant wavelength λd, excited purity Pe, color difference ΔE*ab, lightness difference Δ L*, chromaticity difference ΔC*ab, hue difference ΔH*ab, Hunter system L, a,b ● Measure ISO(R457)and Rz ● Measure CIE (W10 and Tw10) ● Measure ceramic’s whiteness ● Measure the whiteness of building materials and non-metallic mineral products ● Measure Yellowness YI ● Measure Hunter whiteness ● Measure opacity op ● Measure transparency T ● Measure light scattering coefficient S ● Measure optical absorption coefficient A ● Measure ink absorption value
