Color PhotoMeter

A color photometer quantifies color by measuring the light reflected or transmitted from an object and analyzing its spectral composition. It is used for color matching and quality control of products such as paints and inks to ensure color consistency between batches.
Selection
When selecting a color spectrophotometer, consider matching the measurement aperture to the sample size, ensuring inter-instrument agreement for data consistency, covering actual usage conditions with the observation light source, balancing portability with fixed measurement needs, and ensuring data software compatibility with existing workflows.
