HD-A822-2
HAIDA
DIGITAL WHITENESS TESTER
INTRODUCTION
Measure the whiteness, yellowness, color and color difference of objects, as well as the opacity, transparency, light scattering coefficient, light absorption coefficient and ink absorption value of paper. It is widely used in papermaking, printing, ceramics, chemical industry, textile printing and dyeing, building materials, food, salt and other industries.
1. Measure the reflected color and color difference of objects.
Can display or print: Diffuse reflection factor Rx, Ry, Rz; Stimulus Value Y10, X10, Z10; Chromaticity Coordinates X10, Y10, Z10; Lightness L*; Chroma a*, b*; Chroma C*ab; Hue Angle h*ab; Dominant Wavelength λd; Excitation Purity Pe; Color Difference ΔE*ab; Lightness Difference ΔL*; Chroma Difference ΔC*ab; Hue Difference ΔH*ab; Hunter System L, a, b.
2. Measure ISO brightness (blue whiteness R457) and Z whiteness (Rz), which can measure the fluorescent whitening degree produced by the emission of fluorescent substances in the fluorescent whitening sample.
3. Measure CIE whiteness (Gantz whiteness W10 and color cast value TW10); Ceramics Whiteness; Whiteness of building materials and non-metallic mineral products; Hunter Whiteness WH; Yellowness YI.
4. Measure Opacity (OP); Transparency (T); Light Scattering Coefficient (S); Light Absorption Coefficient (A).
5. Measure Ink Absorption Value.
