What is the difference between a coating thickness gauge and a film thickness gauge
What is the difference between a coating thickness gauge and a film thickness gauge? The film thickness gauge and the coating thickness gauge are the same product, and they are called differently, just like the gloss meter, everyone will call it a gloss meter, a gloss meter, and a gloss tester.
Generally speaking, the film thickness gauge is a kind of product with the coating thickness gauge.
The film thickness meter generally measures the thickness of the oxide film layer, common aluminum-based, copper-based oxidation, when measuring, use the coating thickness meter to select the N (non-magnetic) probe, so that the measurement of aluminum-based and other oxide layers is also called a film thickness meter.
Under normal circumstances, the coating thickness gauge has two measurement principles, with F and N probes, or FN integrated probes. The oxide layer is generally a few microns to more than ten microns, but the error of ordinary coating thickness gauges is relatively large, so it is necessary to use a high-precision coating thickness gauge to measure the oxide layer, such as the PD-CT2 coating thickness measurement of Zhongke Pudao The instrument can measure the oxide layer.
The two are only slightly different according to the material, but many users do not understand each other and call each other.
