At present, the common gloss meters on the market mainly include 20°, 60° and 85° measurement angles. Different measurement angles are suitable for surfaces with different glosses. For industries such as paper, 45° and 75° measurement angles are used. Due to the different measurement angles, the gloss values we measure on the surface of the object are different. In order to accurately assess the surface gloss of the object, it is necessary to choose a gross meter with a suitable measurement angle.
