What is the measurement principle of the gloss meter? What are the main uses and scope of application? Gloss is a property of the surface of an object. In order to detect the level of gloss, we need to use a professional gloss meter. The following is a brief introduction to its working principle and use!
What is the measurement principle of the gloss meter?
Gloss meter, also known as gloss meter, gloss tester, etc., is an optical instrument that specializes in checking the surface gloss of objects, and is widely used in ceramics, paints, coatings, stone, electronics and other industries.
Gloss is a physical quantity that evaluates the ability of a material surface to reflect light under a set of geometrically specified conditions, with directional selective reflection properties. The gloss we usually say refers to "mirror gloss", so the gloss meter is sometimes called "mirror gloss meter". Therefore, in order to detect the glossiness of the surface of an object, components such as a light source emitting device, a reflected light receiver, and a data analyzer are required. Let's take a look at the working principle of the gloss meter:

The main purpose and scope of application of gloss meter:
Gloss is a relatively common reference index in the industry, such as metal processing, ceramic products, paint coatings, textile dyeing, etc., all have requirements for gloss. Different industries have different standards for gloss. If there is no special regulation in the industry, we generally refer to different standards according to the angle of gloss measurement:
1. The reference standard of gloss tester 20°: DIN-67530, ISO-2813, ASTM-D2457GB9754, GB8807, ISO-8254, ASTM-D523, it is mainly used for high gloss ink, paint, paper, plastic, stone , Light cast coated paper and so on.
2. The reference standard of gloss tester 45°: ISO-2767, GB8941.2, ASTM-D2457, ASTM-C346, GB8807 It is mainly used for the measurement of marble, ceramics, plastics, aluminum alloys and aluminum oxide surfaces, etc.
3. The reference standards of gloss tester 60° ISO-2813, DIN-6750, ASTM-D2457, ASTM-C584, ASTM-D523, GB9754, GB8807, GB9966 are mainly used for medium gloss coated paper, marble, ceramics, Paints, inks, plastics, etc.
Fourth, the gloss tester 85 ° is ISO-2813, DIN-67530, ASTM-D523GB9754, which is mainly used for camouflage coatings, low gloss paints and so on.
Gloss can be divided into three types: high gloss, medium gloss and low gloss tester according to the measurement angle. The gloss meter selected for different surface gloss will be different. Generally speaking, choose a 20° measurement angle for high-gloss objects, 60° for medium-gloss objects, and 85° for low-gloss objects. Each range is best measured in its own angle. To know which angle is best to measure at, start at 60°. If the result is between 10-70GU, the coating can be called semi-gloss and it is best measured at this angle. If the result is less than 10GU, the product is called low gloss and should be measured at 85°; if the result is above 70GU, the product is high gloss and is best measured at 20°. All angles are calculated from vertical angles.
