Interpretation of Core Selection Indicators for Colorimeters

Measurement Accuracy (dE/ΔE): The smaller the value, the higher the match between the color measured by the colorimeter instrument and human visual perception. Generally, dE < 1.0 is regarded as the industrial passing line, while dE < 0.5 falls into the high-precision level. 

Measurement Structure: D/8 (integrating sphere structure) is the universal standard, which includes two modes: SCI (Specular Component Included, with specular reflection light) and SCE (Specular Component Excluded, excluding specular reflection light). 45/0 (ring illumination) simulates the human eye's viewing angle and is more suitable for judging reflective materials. 

Repeatability: It refers to the difference in color results when measuring the same point multiple times. The equipment can achieve ΔE < 0.08, ensuring highly reliable measurement results. 

Illumination Source and Viewing Angle: It is recommended to choose the combination of CIE standard light source D65 (simulating daylight) and a 10° viewing angle. 

Application Scenario Requirements: It is necessary to clarify the purchase purpose (quality inspection? R&D? material evaluation?) and the usage environment (laboratory, workshop or field work?).
