The curved surface pinhole gloss meter is an instrument used to measure the glossiness of the surface of the object. It judges the glossiness of the surface of the object by measuring the intensity and angle of the reflected light on the surface of the object. The following are the key points and precautions for the selection of surface small hole gloss meter:
select points
Light source: There are two types of light sources for curved surface pinhole Glossmeters: white light and optical fiber. The white light source is suitable for testing the glossiness of the surface of objects at different angles, while the optical fiber light source is suitable for testing complex shapes or inaccessible objects.
Angle: The measurement angle of the surface pinhole gloss meter is usually 20 degrees, 60 degrees and 85 degrees, and different angles are suitable for different object surfaces. For example, 20 degrees is suitable for testing high-gloss surfaces, 60 degrees is suitable for testing medium-gloss surfaces, and 85 degrees is suitable for testing low-gloss surfaces.
Resolution: Resolution refers to the minimum amount of change that a measuring instrument can detect, usually in units of GU, and the smaller the resolution, the more accurate the measurement result.
Accuracy: Accuracy refers to the gap between the measurement result and the actual value, usually in GU or percentage. The higher the accuracy, the more accurate the measurement result.
Precautions
Test environment: The curved surface pinhole gloss meter needs to maintain stable environmental conditions during the test, including temperature, humidity, light, etc. Try to avoid testing in windy or dusty environments.
Standard plate: When using a curved surface small hole gloss meter for testing, it is necessary to use a standard plate for calibration to ensure the accuracy of the test results.
Cleaning: Keep the optical path of the curved surface pinhole Glossmeter clean, and clean and calibrate it regularly to ensure the accuracy of the measurement results.
Scope of use: Different surface pinhole gloss meters have different scopes of use and limitations, which need to be understood clearly when choosing, and choose according to needs. At the same time, it is also necessary to choose different curved surface small hole gloss meters according to different usage occasions and requirements.
