Coating thickness testing on small parts is more difficult than testing other products with large contact surfaces. The contact surface of a conventional coating Thickness Gauge probe is more than ten millimeters, while small parts are often small in size, with a contact surface of only a few millimeters , and even two or three millimeters. In order to ensure the accuracy of the test, the basic requirement for coating thickness measurement is that the measured surface of the sample is larger than the contact surface of the probe, otherwise the test results will have large errors.
Therefore, generally for the coating thickness measurement of small parts, special small probes should be selected. At present, the coating Thickness Gauge brands at home and abroad can test the coating thickness of small parts, but relatively speaking, some imported brands do To a slightly higher technical level, such as EPK, Defelsko.
Below is a selection of coating Thickness Gauge models that can test the coating thickness of small parts in the northern and southern tides.
