Multi angle gloss meter GRM-2000 allows users to measure and analyze the specular reflection (gloss level) at 3 different incidence angles (20/60/85°) to suit a wider range of materials, including extremely matte and glossy surfaces.
Operation is easy. Select the required angle of incidence and press the ‘measure’ key. A light beam is transmitted at the prescribed angle onto the test surface and is reflected into the receiver sensor. The corresponding Gloss Unit (GU) value is displayed on screen in a matter of seconds.
The higher the GU value, the greater the glossiness is said to be. ASTM D523 dictates that if your gloss reading at 60 degrees is more than 70 GU, then it is considered to be high gloss and should be remeasured at 20 degrees angle. Alternatively if your gloss reading is less than 10 GU, it is considered to be matte and should be remeasured at 85 degrees.
Generally, 20° applies to High Gloss Materials, 60° applies to Medium Gloss Materials, 85° applies to Low Gloss Materials. Two additional angles are used for other materials. An angle of 45° is specified for the measurement of ceramics, films, textiles and anodised aluminium, whilst 75° is specified for paper and printed materials.
Common use of multi-angle Gloss Meter is in quality assessment. It is able to verify finishing polish on flooring products such as tiles, stone and pavers. It is also used in the production of windows, various painted products, in the printing industry (glossy magazines, signage etc) and automotive industries.
