Papermaking ColoriMeter

Paper colorimeters measure the spectral data of light reflected from the paper surface using photoelectric sensors, calculating chromaticity coordinates and color difference values. They are used to detect paper color consistency and whiteness indicators, as well as to control dye addition and batch color stability during production.
Selection
When selecting, consider matching the measurement aperture to the sample size, ensuring the built-in light source type complies with industry standards, and the instrument's repeatability error is less than the production tolerance. Check if it supports paper-specific indicators such as opacity and gloss measurement, and ensure the operation interface is suitable for the workshop environment.
