The science behind the Glossmeter - Glossmeter development starts with an understanding of the basic principle of gloss. Surface textures, translucency and color all influence the visual perception of a surface but also influence the fine optics of the glossmeter. Microscale surface deformations cause scattering of light and divide it into specular and non-specular. This is the fine threshold where the TQC glossmeter is able to determine the gloss at the highest accuracy level. It is common practice to use a 60° angle gloss meter for almost every application. Most specifications specify a gloss level measured at 60° which often deviates from international standards. The measuring angle should always be mentioned in combination with a gloss value.

Sending and receiving - To determine the best light source and detector setup components from suppliers all over the world have been tested. Spectral sensitivity, stability and linearity all proved to be exceptionally stable using the TQC glossmeter.

Standardization - In order to guarantee the TQC glossmeter to be one of the most stable meters availalbe and fullfills all the demands of the ASTM, DIN and ISO standards, TQC joined all of the standardization bodies and are actively involved in testing criteria relating to the standards ensuring the highest test of conformity.

Precision engineering - In order to get the best stability the TQC glossmeter’s unique double frame system has been engineered with the highest precision. Carefully controlling the interior of the light patch helps to give the TQC glossmeter robust and stable structure.

Ten thousands of readings - To assess the quality of the TQC glossmeter we took thousands of readings on certified substrates to test stability, reliability and durability. With or without shock testing the TQC glossmeter proved to have the ultimate level of performance.
