Color Difference Meter

A colorimeter measures the tristimulus values of light reflected or transmitted by an object to calculate color differences from a standard sample. It is used for product color quality control in industries such as coatings and plastics to ensure color consistency between batches.
Selection
When selecting, consider matching the measurement aperture to the sample size, choose a model that includes the required color space (such as CIELAB), confirm the instrument's inter-instrument agreement range, check compliance with industry standards, and evaluate the need for portability versus a fixed setup.
