How do I choose a Gloss Meter?You first require a flat surface of approximately 2 by 0.5 (50 x 10mm) to position a glossmeter properly on a surface. If the surface area you have is smaller, then please choose our 3nh brand small aperture model NHG60M
High Gloss - 20°
The acute measurement angle of 20° gives improved resolution for high gloss surfaces. Surfaces that measure 70 GU and above at the standard angle of 60° are often measured with this geometry. The 20° angle is more sensitive to haze effects that affect the appearance of a surface. The different gloss of these two samples is more clearly shown in the 20° readings.
