The gloss Tester is an instrument used to measure the reflected light on the surface of the material, and can be used to measure the smoothness, gloss, texture, etc. of the surface of the material. The following is a detailed introduction to the selection points and precautions of the gloss Detector.
select points
Measuring range: Different gloss Detectors have different measuring ranges, which need to be selected according to actual needs. If you need to measure the gloss of many different materials, it is recommended to choose an instrument with a wide measurement range.
Accuracy: The accuracy of the gloss Tester is a very important selection indicator. Usually, the more accurate the instrument is, the more expensive it is, and it needs to be selected according to actual needs.
Resolution: Resolution refers to the ability of the instrument to identify subtle changes in gloss. The higher the resolution, the smaller the difference in gloss can be detected, but the price will increase accordingly.
Repeatability: Repeatability refers to whether the data obtained by the instrument are consistent in multiple tests of the same sample. For application scenarios that require a large number of tests, instruments with good repeatability are more important.
Convenience of operation: Considering the use scene of the instrument and the level of personnel operating skills, choose a gloss Detector that is easy to operate and easy to use.
Precautions
Read the instruction manual carefully before use, and calibrate and maintain the instrument as required to ensure the accuracy and stability of the test results.
The test sample should be kept as flat as possible, free of impurities and damage, and the surface of the sample should be kept dry and clean to ensure the accuracy of the test results.
When measuring, you should avoid directly touching the test site with your fingers. You can use special test fixtures or gloves and other tools to prevent finger grease and dirt from affecting the test results.
When measuring multiple samples, it is necessary to calibrate the instrument to the zero point first, and perform zero point calibration before each measurement, so as to avoid the previous test results from interfering with subsequent tests.
When using the gloss Tester, strong light should be avoided to directly shine on the test part of the instrument, so as to avoid the test results being disturbed by light.
