Product Description

Product Overview

The high accuracy color analyzer is a precision instrument with d/0 geometry for measuring the whiteness, color, and color difference of solid materials. It is widely used in papermaking, printing, textile printing and dyeing, ceramics, building materials, chemicals, grain, salt, and other industries, as well as production and commodity inspection departments requiring solid color and whiteness testing.

Model

ST-WM300

Application Range

Papermaking, printing, textile printing and dyeing, ceramics, building materials, chemicals, grain, salt, and other industries, as well as production and commodity inspection departments requiring solid color and whiteness testing.

Application Functions

• Determine the color and color difference of solids under C light source and D65 light source conditions.
• Measure CIE1931 tristimulus values and chromaticity coordinates under the standard chromaticity system.
• Measure CIE1964 supplementary standard chromaticity system tristimulus values and chromaticity coordinates.
• Measure CIE1976 uniform color space parameters: L*, u*, v*, Cuv, Suv, huv, a, b*, C*ab, hab, and color difference.
• Determine CIE whiteness W10 (Gantz visual whiteness) and skew value Tw10.
• Measure blue diffuse reflection factor D65 brightness and fluorescence brightness of fluorescent brightening materials.
• Measure ISO brightness under C/2° indoor light and fluorescence brightness of fluorescent brightening materials.
• Determine whiteness and color of building materials, non-metallic mineral products, and ceramics.
• Determine whiteness, Lab values, and color difference under the Hunter system.
• Determine whiteness and chromaticity of fibers (with fiber sampler).
• Measure whiteness, chromaticity Lab values, and color difference of powders.
• Measure yellowness index (YI), opacity (OP), light scattering coefficient (S), light absorption coefficient (A), transparency, and ink absorption value.
• Measure reflected optical density Dx, Dy, Dz.
