Papermaking, printing, textile printing and dyeing, ceramics, building materials, chemical, food, salt and other industries industries that need to determine the color and whiteness of solids in Production and commodity inspection department.

● Measure the color and chromatic aberration of a solid under the conditions of C light source and D65 light source:
● Tristimulus values and chromaticity coordinates under CIE1931 standard color system;
● CIE1964 supplements the tristimulus values and chromaticity coordinates of the standard chromaticity system;
● L*, u*, v*, C*uv, Suv, huv, a*, b*, C*ab, hab and color difference of CIE1976 uniform color space.
● Measure CIE whiteness (Gantz visual whiteness) W10 and color cast value Tw10
● Measure the brightness of blue diffuse reflection factor D65 and the fluorescence brightness of fluorescent whitening materials.
● Measure the ISO brightness and the fluorescence brightness of fluorescent whitening materials under the condition of indoor light C/2°.
● Measure the whiteness and color of building materials, non-metallic mineral products, and ceramics.
● Measure the whiteness, Lab and color difference under the Hunter system.
● Measuring the whiteness and chroma of the fiber (matching Fiber Sample Holder).
● Measure the whiteness, chromaticity, Lab and color difference of the powder.
● Measure yellowness YI, opacity OP, light scattering coefficient S, light absorption coefficient A, transparency, ink absorption value.
● Measure the reflected optical density Dx, Dy, Dz.

● Imported concave flat field grating, photoelectric display sensor, pulse xenon lamp and other components are used to ensure the basis of equipment accuracy.
● The circuit adopts the ARM+FPGA dual-core scheme to ensure the calculation capability and the timing accuracy of sampling.
● The stepping motor controls the amount of ultraviolet radiation, automatically and accurately controls the amount of radiation, and the fluorescent brightness is tested by one button.
● The instrument is operated by complete PC-side software, and the number of tests data storage space is not limited;
● Convenient to check and print historical measurement data, the number of standard samples is not limited;
● Easy to upgrade when software functions need to be added
● Equipped with light absorber to eliminate specular reflection.
