Requirements for the use of coating thickness gauges are as follows
In order to better apply the coating thickness gauge, some requests for the application of the coating thickness gauge are mentioned in the product description, in order to avoid user manipulation and the formation of inaccurate measurement results of the coating thickness gauge. To this end, the editor will introduce the application requirements of coating thickness gauges for everyone.
Application request for coating thickness gauge:
1. For the metal characteristics of the magnetic substrate, the magnetic properties of the standard sheet's substrate metal are similar to those of the specimen's substrate metal, and the nominal roughness is also similar. For the eddy current method, the electrical properties of the standard substrate metal and the specimen substrate metal are also similar.
2. To ensure that the thickness of the base metal does not exceed the critical thickness, a 1-point or perhaps 2-point method can be used to stop calibration.
3. The edge effect cannot be stopped at the gradient of the specimen, such as the edge, hole, and inner corner.
4. Curvature cannot be measured on the curved surface of a workpiece.

The readings measured each time may not be completely identical, and some may be due to manipulation techniques and the average degree of the substrate. Therefore, when applying a coating thickness gauge, it is necessary to take how many readings in each measurement area. Another issue is the uneven thickness of the covering layer, which requires us to stop measuring multiple times within any given area. The roughness of other surfaces can also affect the measurement results.
6. Before using a coating thickness gauge to measure the coating, the first step is to sweep away any nominally attached materials, such as dust, grease, and decaying products. During the clean time, be careful not to damage the coating that needs to be measured.
The above content introduces the application request of the coating thickness gauge, hoping to be helpful for the application of users.
