What distinguishes a coating thickness gauge from a gauge for measuring film thickness?
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, the common aluminum-based, copper-based oxidation, when measuring, use the coating thickness meter to select the N (non-magnetic) probe, so that the aluminum-based and other oxide layers are 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.
The difference between coating thickness gauge and non-destructive coating thickness gauge:
Coating thickness gauge, mainly used in the surface treatment industry, is used to measure the coating thickness of metal or plastic surfaces.
Non-destructive coating thickness gauges are divided into two types: magnetic and eddy current, and there is also a dual-purpose type of magnetic eddy current. It is often used to measure the thickness of the nominal coating where the substrate is metal, so it is also called a coating thickness gauge.
The magnetic thickness gauge is designed to measure the thickness of the coating under magnetic metals such as steel (except for magnetic metals such as steel and nickel), and the coating under non-magnetic copper, aluminum, tin, etc. cannot be measured. The eddy current thickness gauge is designed to measure the thickness of the insulating layer on non-magnetic metals, such as copper and aluminum (the coating must be non-conductive).
