The Micro-Gloss Meter has been the unsurpassed industry standard in gloss measurement for many years. It is the only glossmeter combining highest accuracy, ease-of-use and multiple functionality – essential for today`s testing requirements.
Gloss Meter Family - Micro-Gloss Glossmeters
A glossmeter measures the specular reflection. The light intensity is registered over a small range of the reflection angle. Our comprehensive range of competitive and reasonably priced gloss meters include economical models as well as advanced versions measuring single angles or TRI angles.
The measurement results of a gloss meter are related to the amount of reflected light from a black glass standard with a defined refractive index, and not to the amount of incident light. The measurement value for this defined standard is equal to 100 Gloss Units (calibration).
The intensity is dependent on the material and the angle of illumination. In case of non-metals (coatings, plastics) the amount of reflected light increases with the increse of the illumination angle. The remaining illuminated light penetrates the material and is absorbed or diffusely scattered dependent on the color. Materials with a higher refractive index can have a measurement value above 100 gloss units (GU), e.g. films. In case of transparent materials the measurement value can be increased due to multiple reflection in the bulk of the material. Due to the high reflection capabilities of metals values of up to 2000 GU can be reached. For these applications it is common to document the measurement results in % reflection of the illuminated light.
Gloss meters and their handling procedures had to be internationally specified to allow comparison of measurment values. The angle of illumination is of high influence. In order to obtain a clear differentation over the complete measurment range from high gloss to matte, 3 different geometries, i.e. 3 different ranges, were defined:
In this case study 13 samples were visually ranked from mat to high gloss and measured with the 3 specified geometries. In the steep slopes of the curves the differences between the samples can be clearly measured, while in the flat part the measurement geometry no longer correlates with the visual.

QualiGloss series for gloss measurement
Gloss is a measure of the proportion of light that reflects from a surface: a mirror has high gloss, supplying enough light to accurately display an object, whereas surfaces such as chalk have less gloss because the light is diffused. In many manufacturing and craft industries throughout the world, gloss meters provide a quantifiable way of measuring the gloss intensity of products and components.
The Gloss Meter - QualiGloss series offers multiple instruments for measuring the reflection of light striking an object at different angles: the QualiGloss I for 60°, two models of Gloss Meter - QualiGloss II for 20°/60° and 60°/80°, and the Gloss Meter - QualiGloss III for a comprehensive unit that covers 20°, 60°, and 80°. With this diverse range of models, QualiTest is able to help companies meet international technical standards for the use of gloss on many types of materials and industrial coatings applications. These units are equipped with intelligent software that auto-calibrates settings and provides real-time feedback to users, allowing operators to effectively measure the amount of reflected light from a black glass standard with a defined refractive index.
These devices can be optimized to define the precise illumination and viewing conditions of a wide variety of materials, such as plastic and wood surfaces, ceramic tile, marble, granite, and paper, as well as coating and finishing surfaces such as paints, varnishes, and printing ink.
