A high-precision paint thickness measurement tool can achieve higher accuracy for coating thickness measurement on the surface of the measured object. This article introduces the application principle and non-destructive testing of high-precision paint thickness measurement tools.

High-precision paint thickness measurement tool can measure the thickness of coating on the surface of objects. High-precision paint thickness measurement tools are used in different scenarios such as scientific research laboratories or construction sites. Compared with ordinary paint thickness measurement tools, high-precision paint thickness measurement tools are characterized by more accurate measurement results and higher measurement resolution.
        At present, the principles of paint thickness measurement tools are generally as follows: The first is the radioactive thickness measurement method, which mainly uses ray penetration detection. The paint thickness measurement tool using the radioactive thickness method is mainly used in some special environments. It requires high measurement parameters. However, the paint thickness measurement tool using the radioactive thickness method is expensive. So it is not widely used. The second is the ultrasonic thickness measurement method. This paint thickness measurement tool detects the coating thickness according to the frequency change of the ultrasonic wave. The advantage is that it can be applied when there are multiple coatings on the surface of the object. There are also paint thickness measurement tools using microwave laser thickness measurement and electrolytic thickness measurement. The paint thickness measurement tool using the microwave laser thickness measurement method is under development and has not been fully put into production. The paint thickness measurement tool using the electrolytic thickness measurement which is destructive testing.
        The high-precision paint thickness measurement tool mainly uses the magnetic thickness measurement method and eddy current thickness measurement method, which is suitable for the thickness measurement of non-magnetic conductive layer and non-conductive layer. The measurement results are highly accurate, so they are more widely used.

High-precision paint thickness measurement tools using magnetic thickness measurement and eddy current thickness measurement are more affordable and more accurate than paint thickness measurement tools using radioactive thickness measurement and other traditional thickness measurement methods. When making a purchase selection, when the workpiece itself is a magnetically permeable material, a high-precision paint thickness measurement tool using magnetic thickness measurement should be selected. If the workpiece is a conductive body, a high-precision coating thickness measurement using eddy current thickness measurement should be selected. This can make the measurement results of the paint thickness measurement tool more accurate, ensure that the instrument numerical display is stable during the measurement process.
        High-precision paint thickness measurement tool is a non-destructive test for coating thickness measurement on the surface of an object, which will not cause any damage to the measured object. For example, if the thickness of the waterproof coating on the cement surface is to be tested, if the thickness measurement is performed by means of AC film measuring instrument, DC film measuring instrument, PIG, etc., it will cause damage to the surface of the object and directly affect future use. The paint thickness measurement tool can avoid this damage without any interference to the performance of the object.
        The high-precision paint thickness measurement tool can measure the coating thickness of very small or thin objects. For example, if you want to know the wall thickness of some products, you can use a high-precision paint thickness measurement tool for non-destructive testing. This kind of detection has high accuracy, convenient application. It is more and more welcome.
