Color Measurement System

A colorimeter captures spectral data of light reflected or transmitted by an object through a photoelectric sensor and converts it into chromaticity values. It is used to detect color consistency in products such as paints and plastics, thereby controlling color differences during production.
Selection
When selecting, consider matching the measurement geometry to the sample type to ensure instrument repeatability and inter-instrument agreement meet standards. Choose an instrument with specular reflection mode based on the material's gloss, verify that its measurement range covers the industry's color gamut, and ensure compatibility with existing quality control processes.
