PCE-WSB 1 Whiteness Meter
Measures the whiteness degree of blue light (Wb = R457) / Meets ISO 2470 and ISO 3688 standards / Compact, lightweight and user-friendly
PCE-WSB 1 is a portable handheld battery-powered whiteness color meter used to measure the brightness level of paper, cardboard, cellulose, pulp, textiles, paint, enamel, plastic, porcelain, cement, concrete, building materials, chemicals, powders, talc, starch, flour, salt, detergents, cosmetics and other non-metal substances.
Ideally used on flat surfaces, the whiteness meter features an easy-to-read liquid crystal display (LCD) screen. The device determines the brightness level by measuring the intensity of the light reflection diffused on a scale of 100. The level of brightness of an absolutely black surface is defined by the meter as 1. Included with the meter are black, white and brilliance standards for DIY calibration as needed to ensure accurate, repeatable measurements are consistently obtained.
