A small hole gloss meter is an instrument used to measure surface gloss. The surface gloss is calculated by focusing the light reflected from the surface of the sample on a small hole and measuring the intensity of the light passing through the small hole. The following are the selection points and precautions of the small hole gloss meter:
select points
Measuring range: Different pinhole gloss meters have different measuring ranges, and an appropriate range needs to be selected according to actual needs.
Accuracy: The accuracy of the small hole gloss meter is also a key selection point, and the appropriate accuracy needs to be selected according to the specific requirements of the application.
Small hole size: The small hole size is also an important factor affecting the measurement accuracy, different sizes of small holes are suitable for different types of samples.
Convenience of operation: The convenience of operation of the small hole gloss meter is also a factor that needs to be considered, and it is necessary to choose an instrument that is easy to operate and maintain.
Data output method: different pinhole gloss meters have different data output methods, some can directly output data to the computer, and some need to manually record data, you need to choose the data output method that suits your use.
Precautions
Calibration: Calibration is required before using the small hole gloss meter to ensure the accuracy of the measurement results.
Sample surface preparation: The sample surface needs to be kept clean and smooth to avoid affecting the measurement results.
Measurement environment: The pinhole gloss meter needs to be used in an environment with relatively stable light to avoid the influence of ambient light.
How to use: The use of the small hole gloss meter needs to be operated in the correct way to avoid inaccurate measurement results caused by misoperation.
Instrument maintenance: The small hole gloss meter needs regular maintenance and maintenance to maintain the performance and accuracy of the instrument.
