纸张光学性能测定仪

Brightness Testing — Paper Analysis Equipment

Optical properties sell printing and writing papers. Our instruments measure ISO brightness, whiteness, opacity, colour and gloss for mill QC and customer certificates. Diffuse brightness follows ISO 2470-1, while TAPPI T452 covers directional readings; whiteness is set up for ISO 11475. We match geometry and illuminant to the method you report.
