PCE WSB 1 Whiteness Meter

PCE WSB 1 Whiteness Meter

The PCE WSB 1 whiteness meter is an optimal solution designed to determine whiteness levels through diffuse light reflection intensity based on standard measurement scales (typically referencing blue light whiteness Wb = R457). The device operates based on photometric methods compliant with international standards such as ISO 2470 and ISO 3688, helping to perform quick and accurate tests without damaging the sample.
