Automatic whiteness, chromaticity, and yellowness meter for ink absorption value detection

ST001E fully automaticBaiduA colorimeter is used to measure the whiteness, yellowness, color, and color difference of an object. It can also measure the opacity, transparency, light scattering coefficient, light absorption coefficient, and ink absorption value of paper. Widely used in industries such as flour, starch, mineral powder, papermaking, printing, ceramics, chemical industry, textile printing and dyeing, building materials, grain, salt production, etc.Automatic whiteness, chromaticity, and yellowness meter for ink absorption value detection

The specific functions of the instrument are as follows：

lMeasure the color and color difference reflected by objects, can display or print

lmeasurementISO brightness (blue light whiteness R)₄₅₇）AndZ-whiteness (Rz) can measure the fluorescence whitening produced by the emission of fluorescent substances in fluorescent whitening samples.

lmeasurementCIE白度（甘茨白度W₁₀And color deviation valueT_W10）.

lMeasure the whiteness of ceramics.

lMeasure the whiteness of building materials and non-metallic mineral products.

lMeasure Hunter whitenessWH。
