The KERRO KWM-2 Whiteness Meter is a digital benchtop instrument for objective measurement of whiteness and brightness of paper, cardboard, textiles, plastics, powders, ceramics, chemicals and other non-metallic materials. It uses the photoelectric principle, D65 light source, R457 blue-light whiteness measurement and 45°/0° geometry.

Product Overview

The KERRO KWM-2 Digital Whiteness Meter is designed to provide objective measurement of the whiteness level of white and near-white materials. It uses a D65 light source and R457 blue-light whiteness measurement under 45°/0° measuring conditions.

The KWM-2 is configured as a portable benchtop whiteness meter and is suitable for measuring materials including paper, cardboard, cellulose, pulp, textiles, plastics, ceramics, chemicals, powders, flour, starch, detergents and other non-metallic substances.

Its high-precision optical system and positioning structure are designed to improve measurement repeatability and stability. The instrument supports both laboratory and production environments through AC/DC power operation and includes a low-voltage indication function.
