FAQs About YG45 Gloss meter
Gloss level is the extent of reflectance of light on a surface. It measures the shininess or dullness of a finish, from flat or matte to high gloss. It is important in aesthetic, functional, and quality control applications.
The gloss of the paint is defined by the measurement of light reflection at the surface of the paint with the help of a gloss meter. The angle and quantity of light reflected determine the level of gloss, with smoother and reflective surfaces having a higher level of gloss.
A gloss meter measures the amount of light reflected from a surface at a specific angle. It's commonly used to assess surface finishes such as paint, coatings, plastics, and paper for consistency, quality control, and visual appearance evaluation.
A paint gloss meter is used to measure the level of paint gloss, whereby it reflects light at some angles, such as 20°, 60°, or 85° angles, and measures the intensity of that light. To measure surface sheen, the level of gloss is compared to standards that are calibrated and reported in units of gloss (GU).
Powder paint gloss levels are classified as:
● Flat: 0–10 GU
● Satin: 11–40 GU
● Semi-gloss: 41–70 GU
● Gloss: 71–85 GU
● High Gloss: 86+ GU
These are measured at a 60° angle for standardization.
