纸张 ISO 白度仪
Pulp and paper brightness specifications are written in ISO brightness, a value read under illuminant C with 457 nm as the effective wavelength, with diffuse illumination and 0° viewing. This tester measures a roughly 30 mm area with ±0.1% reflectance repeatability, and ships with a black trap plus a certified white reference.
