How to choose a coating thickness gauge
The coating thickness gauge is divided into magnetic thickness measurement method and eddy current thickness measurement method. Magnetic is to test non-magnetic coating on magnetic substrate, just like paint on steel, steel is magnetic, paint is non-magnetic, and eddy current is to test non-ferrous metal substrate Testing non-conductive insulating coatings. Just like the paint on aluminum, aluminum is a non-ferrous metal, and the paint is non-conductive. When selecting a product,
Many customers don't know which one they need to test their products. There are too many products in the market, which is easy to be confused. Here are a few situations for you:
1. What to test (the thickness of the product? Or the thickness of the layer of paint on the product) The first step is to clarify whether the coating thickness gauge or the overall thickness of the substrate is tested when needed.
2. The substrate of the test (is it magnetic (steel, iron, alloy and hard magnetic steel, etc.) or aluminum (such as copper, aluminum, zinc, tin, etc.) The second step is to distinguish what the substrate is? This can distinguish whether it can be tested .
3. What is the material of the surface to be tested? The third step is to know what the material of the coating is, whether it is magnetic or non-magnetic or conductive, which is beneficial to product selection.
4. The parameters of the test The fourth part is about how thick the coating is to be tested and whether the product can be measured.
5. The price of the product The fifth step is the customer's after-sales and price trend of the product. Through the above analysis, we not only know the function of the coating thickness gauge, but also roughly understand how to choose it. Regarding the application range of the coating, It is far more than just manufacturing, metal processing, chemical industry, commodity inspection and other testing fields. In our future world, its appearance represents a professional reform.
