How to Use a Paint Film Measuring Instrument?
1 Answers
The main methods for using a paint film measuring instrument are as follows: 1. Magnetic Thickness Measurement: Suitable for measuring the thickness of non-magnetic coatings on magnetic substrates, such as steel, silver, and nickel. This method offers high measurement accuracy. 2. Eddy Current Thickness Measurement: Suitable for measuring the thickness of non-conductive coatings on conductive metals. The accuracy of this method is lower than that of the magnetic method. 3. Ultrasonic Thickness Measurement: This method is less commonly used for measuring coating thickness, and only a few manufacturers abroad produce such instruments. 4. Electrolytic Thickness Measurement: This method is not non-destructive, as it requires damaging the coating, and generally offers lower accuracy. 5. Radiometric Thickness Measurement: Instruments using this method are very expensive and are typically used in special applications.
