Micro-gloss meter manufacturers tell you that Gloss is quite different from the machining industry's overview of "finish" or "roughness," which is a measure of the tiny unevenness of a material's surface.

Micro-gloss meter manufacturers tell you that first, calibrate with a calibration plate with a known gloss value, and know the light intensity of the light source through the calibration process.
Micro-gloss meter manufacturers tell you that the purpose of gloss meter calibration is to eliminate the influence of changes in the intensity of the light source and environmental changes each time the machine is turned on. This step of calibration is very important. If the calibration is not done well, the measurement will be greatly affected.
Therefore, Micro-gloss meter manufacturers tell you that in the process of calibrating the gloss meter, it is necessary to ensure that the bottom surface of the gloss meter and the calibration plate are in very close contact, and we also ensure the processing accuracy of the gloss bottom surface in the research and development.
The above information is the Micro-gloss meter manufacturer's introduction and analysis of the precautions for calibration of gloss meter, hope it helps you.
