Color Capture Instrument

A color capture instrument measures the spectral data of light reflected or transmitted from an object's surface using optical sensors and a spectroscopic system, converting it into digital color values. It is used to record, transmit, and compare color information, assisting in color quality control and formulation management in industries such as coatings, plastics, and textiles.
Selection
When selecting, focus on matching the measurement aperture to the sample size, consider the usage scenarios for portable or benchtop models, verify the instrument's repeatability indicators, confirm that the accompanying software meets data management needs, and assess the brand's technical service capabilities as well as calibration cycle costs.
