2. Usage of Gloss Meter

 

Gloss meter is used to measure the gloss degree of the surface. The angles selected for measurements are different and the results are also different. The larger the angle, the greater the specular reflectance, the higher the gloss value is; and vice versa. Thus, the level of gloss depends not only on the surface properties of the object, but also on the measurement angle. According to the angles, gloss meter can be mainly divided into 20 ° high gloss meter, 60 ° gloss meter and 85 ° low gloss meter.
