Coating Thickness Gauge

A coating thickness gauge measures the thickness of coatings on substrates using principles such as magnetic induction, eddy current, or ultrasonic waves. The magnetic induction method is used for non-magnetic coatings on steel substrates, the eddy current method measures insulating coatings on non-ferrous metal substrates, and ultrasonic waves are suitable for multi-layer structures. Its function is to detect coating uniformity, and it is applied in metal processing, automotive painting, and quality control.
Selection
When selecting a coating thickness gauge, it is essential to consider the substrate type. Magnetic induction types are suitable for steel, while eddy current types are used for non-ferrous metals. Universal types combine both methods. Choose the measurement range based on the coating thickness, with 0-2000 microns being common. Assess the required accuracy, typically within ±1-3%. Portable models are ideal for on-site use, while fixed types are better suited for laboratory environments. Determine whether statistical functions and data output capabilities are necessary.
