A1: What is a gloss meter?
Q1: Gloss meters are used to measure the surface gloss of materials. A gloss meter is used to measure the reflectance of light on the surface of an object, that is, the specular gloss. Depending on the angle of incidence selected during measurement, the results are also different. The larger the angle of incidence, the higher the specular reflectance, the higher the gloss, and vice versa.
A2: What are the measurement angles of the gloss meter?
Q2: Gloss meter, mainly contains three measuring angles, respectively 20 °, 60 °, and 85 °, different measuring angles for different glossy object surfaces.
A3: How to choose the measuring angle of the gloss meter?
Q3: For different object surfaces, the suitable measurement angle is not the same, general materials, generally use a 60 ° gloss meter can be measured, high gloss materials, you can choose a 20 ° gloss meter, for low gloss materials, you can choose 85 ° gloss meter.
Tips: How often is a gloss meter calibrated?
A gloss meter is a measuring instrument and should be regularly calibrated according to its usage to ensure the accuracy of the instrument. The calibration period of gloss meter and gloss board generally does not exceed 1 year.
