How to detect the gloss of stone? The detection of stone gloss requires a professional stone gloss meter. There are many types of stone gloss meters, and the prices are different, but the principle is the same.

The stone gloss meter is projected with a 60-degree angle light source and placed on the stone surface during measurement. Through the angle of light source and receiver, the ratio of the reflected light flux of the stone in the specular reflection direction to the reflected light flux of the glass standard sample in the specular reflection direction , which is converted into data by electronic calculation and displayed on the liquid crystal display of the instrument. The display interface of the stone gloss meter has a statistical function, which can display the maximum value, minimum value, average value and standard deviation value of the test. This feature can be used to analyze the uniformity of stone surface gloss.

1) The standard plate of the stone gloss meter must be well protected for the measurement of the gloss meter, and must be
The data of the glossiness standard plate should be used as the reference standard. If the standard plate is inaccurate, the instrument must be inaccurate. Moreover, the gloss of the standard plate is very easy to be stained, so the standard plate of the instrument must be well protected. Generally, a special base is used, and the standard plate is embedded in the base to avoid external pollution and scratches.

2) The stone gloss meter must have the self-diagnosis function of standard plate contamination, that is, if the standard plate is soiled, the instrument can identify and prompt the user to clean the standard plate. Otherwise, the calibration is wrong, and all measurement data will be inaccurate.
