Gloss Meters

Gloss Meters

At NUNES Instruments you will find highly accurate digital gloss meters. Colour and gloss are two different and important parameters to determine the surface conditions and characteristics of the piece that lies in front of you and has to be measured. To ensure a homogeneous impression of a product that consists out of several components, the knowledge of the gloss value of each part is very relevant. Product examples are found for example in the automotive industry, where the components of the vehicle interior are manufactured in different stages of production and then are joined. In the end-product, with respect to their visual appearance, no difference between the individual components should be visible. To achieve this, the use of gloss meter is indispensable. These gloss meters measure colour and gloss to determine the surface characteristics of materials or components. They are easy to use, compact and are solidly built. Gloss meters are specially designed to take measurements on the spot or by professionals on the job and are highly valued by workers in technical services that must take test measurements offsite. These gloss meters can be used on different surfaces, may they be smooth, treated or untreated such as stone, wood, laminates, floors, etc. Principles of measurement of a gloss meter (IG series): Gloss is determined by measuring the reflection of light on a particular surface. This measurement takes the intensity of light reflected from a specific point onto a specimen surface into consideration. According to this, the surface gloss reading of glass with the previously calculated coefficient of 1,567 must indicate the value relative to 100. A plate of black glass is used as the reference surface for calibration with a value of 90 for a measurement of 60° and 84 for a measurement of 20°. If you can't find the gloss meters you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: 09020607000.
