ColoriMeter and Chroma Meter

Colorimeters and color difference meters calculate color coordinates and color differences by measuring the spectral data of light reflected or transmitted by objects. They are used to compare color differences between samples and standard products, ensuring color consistency in industries such as coatings and plastics.
Selection
Select d/8° or 45°/0° optical structures based on measurement requirements; consider aperture size matching the measured object; choose appropriate color difference formulas such as ΔE*ab or ΔE00; confirm instrument inter-instrument agreement and long-term reproducibility indicators; evaluate whether software functions meet data management requirements.
