D8 Diffuse-Reflection Color Difference Meter

Supplier
Jptoe
Category
Measurement Devices
Origin
China

The D8 diffuse-reflectance color-difference meter uses standard d/8° geometry(diffuse illumination/8° collection). SCI(specular component included) and SCE(specular component excluded) modes provide complete color and reflectance data for industrial quality inspection, color-consistency control, and material analysis. It simultaneously measures SCI and SCE optical paths rotated 90° relative to one another. The symmetric SCI path collects all reflected light;the SCE path adds a light trap to exclude specular reflection for more representative material-color measurement.

Key Features

Reflectance/CIE output: simple, intuitive software provides reflectance and CIE chromaticity data for professional analysis. Fast measurement/triggering: <0.5s acquisition and external trigger for coordinated control. Custom measurement area: standard 2×2mm, customizable, with included color-calibration plate for accuracy. Easy integration/low maintenance: multiple mounting holes simplify integration and eliminate manual-operation errors; simple structure lowers maintenance cost. NIM verification: verified by China's National Institute of Metrology; noncontact design prevents sample damage/contamination.
