A sheen meter or sometimes referred to as a gloss meter is an electronic device used to determine the specular reflective characteristics of a surface. The devices work by shining light on a surface at a preset angle, normally 75, 60 and 20 degrees. The light is usually shone at a constant intensity hence obtaining constant data at the opposite direction. This data is then employed in standardizations procedures in different industrial products.
The sheen meter or gloss meter has been a useful tool for manufacturers to determine the level of consistency in their product; thanks to this genius way of quantifying gloss levels. Without the device, it would be difficult for companies to ensure perfect control on some productions. Companies like automotive, ceramic polishing companies and paintings, use the device to ensure they produce what the customer wants. That is, a product that is appealing and inviting.
By a simple press of the button, the device commences shining light on the material and gives an output of full statistical data. Technology on the device has advanced and now there are different designs to measure small, large and curved surfaces. From the data, the manufacturers can employ corrective measures to remove nonconforming surfaces. When the light is shone on the surface, it is expected that the statistics collected will range within accepted average figures to ensure consistency. Depending on the material of the surface that needs to be measured, different geometrics of the sheen meter exist. Metals, non-metals such as ceramics, paint and paper, all have internationally specified measurement geometrics. These materials produce different reflectance hence the light and angle of illumination is varied for different materials. For example, an increase of angle and amount of illumination causes a similar increase of reflectance in nonmetals. It is a little different for metals for they are not as much dependent on angle of illumination. The device produces statistical data after comparing the obtained data to standard gloss units obtained from a standard black glass.
