Spectrophotometric Color Measurement Instrument

A spectrophotometric colorimeter measures the spectral distribution of reflected or transmitted light by illuminating an object with a light source, converting it into color values. It is used for 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, include specular reflection to exclude gloss effects, evaluate inter-instrument differences to ensure data consistency across multiple devices, and check compliance with industry standards such as ASTM E308.
