The new line NauMetrics Gloss Meters, very easy to use and extremely accurate and competitively priced.

Gloss is measured by measuring the reflectance of a material on the incident light beam. The measurement of the reflectance should be done with the following rule: angle of incidence is angle of reflection.
Gloss is highly dependent on the angle at which the material is viewed. If have an observer perpendicular to an object can hardly looks luster, but when he looks almost parallel to the material, there may be a gloss observed.
When measuring the gloss, it is therefore important that the angle has been standardized. Typical angles are 20 °, 60 ° and 85 °. For a high gloss, the gloss is generally by 20 °, resulting in lower gloss measured at 60 °. Matte materials are measured at 85 °.
In addition to the method in remission, the gloss can also be measured by the amount of reflective (according to angle of incidence is angle of reflection) to compare light with the amount of light scattered (which can be seen at other angles than the angle of refraction.
In addition to the angle also plays the width of the incident beam of light a role, so that the measurements from different measuring devices can not be compared with each other. The material is compared, may have no color because the color is also included in the measurement.
ISO 2813 is the standard for the measurement of the gloss paint layers. For paper the method ISO 8254 is the standard for brilliance. Also ISO method 7688 describes the gloss measurement.
Gloss meters should be regularly calibrated, for example, this is done with a gepoleerde, high gloss black glass with a refractive index of n = 1.567. For metal surfaces, however, is a high-gloss gepoleerde aluminum surface, which is provided against corrosion of a transparent quartz layer, is used.
