A1: What is a gloss meter?
Q1: Gloss meters are used to measure the surface gloss of materials. 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: Does gloss meter have an automatic calibration function?
Yes, the gloss meter has an automatic calibration function, but in order to make it more convenient and flexible to use the instrument, it is designed with a function to select whether the power is automatically calibrated or not. That is, when the last shutdown is manual shutdown, the next power on will be automatically calibrated; when the last shutdown is an automatic shutdown after 5 minutes of rest screen, the next power on will not be automatically calibrated. The instrument must be calibrated when there is a change in the instrument's operating environment (such as when there is a drastic change in temperature, altitude, humidity, etc.). To ensure accurate calibration, please use the standard plate provided by the original manufacturer. Dust on the standard plate will affect the calibration effect. Before calibration, please wipe the working surface of the standard plate with a wipe cloth to make sure the working surface is clean.
