Wsb-1 Portable Digital Whiteness Meter Leucometer White Meter#110093

Description
Mainly applied to the surface roughness of the non-color object or powder whiteness
measurement , and can be obtained accurately coincide with the sensation of brightness values.
For the opacity of the paper can be accurately measured . Can be widely used in textile, paint,
chemicals, building materials , paper, cardboard , plastic products, white cement , ceramic,
enamel , talc , starch , flour , salt , detergents, cosmetics and other whiteness measuring
substances.
