The ability of a surface to reflect light without scattering is known as gloss. Gloss is measured by directing a constant intensity light beam at a fixed angle to the test surface and the subsequent amount of reflected light, at the same angle, is determined and represented by a value in GU's (gloss units).

The angle of reflectance required to measure gloss is dependant on the surface finish – highly reflective surfaces typically require a low angle of reflectance (20 degrees) – matt surfaces typically require high angles of reflectance (85 degrees).

Combining accurate gloss measurement with state of the art electronics, the Elcometer 407L Glossmeter is a simple to use powerful gauge.
