The Gloss Meter is a portable precision instrument to detect any degree of brightness on different surfaces from matt to high gloss. For this, the measurement angle of 60 degrees of the Gloss Meter is ideal. At a glance it is often difficult to differentiate the degrees of brightness. The Gloss Meter detects the brightness levels of a painting. However, often minor differences are irrelevant to the naked eye. We should also bear in mind that each person, and therefore each eye,  perceives brightness differently. Some polishing manufacturers advertise about these data, but that is absurd. Different tests have shown different results in a varnished shine, some even without making a measurement. This is due to the different angles of vision of the observer and the light intensity at the time of inspection. So, some coated surfaces perpendicularly seen,  seem opaque, meanwhile if they are seen from almost a horizontal angle, they seem to have much shine. The value of a high-gloss coating is usually between 70 and 100 GU (gloss units)
