What Is a Coating Thickness Gauge?
A coating thickness gauge is a device designed to measure the thickness of coatings on various surfaces. These gauges on magnetic, electromagnetic, and optical principles, catering to different substrates: magnetic gauges for steel surfaces, electromagnetic for non-magnetic materials, and optical for a broad range of substrates. Coating thickness gauges are valued for their non-destructive testing, precision in micrometers, portability, and ease of use.
Widely used in industries such as automotive and appliance manufacturing, construction, painting, and repair services, as well as in research, coating thickness gauges simplify the measurement process. To determine a coating’s thickness, the user places the probe on the target surface, and the device processes and displays the measurement accurately and efficiently.
