Magnetic thickness gauge

A magnetic thickness gauge is a device used to measure the thickness of non-magnetic coatings, such as paint or enamel, on magnetic materials like steel. It works by applying a magnetic field to the surface and measuring how much the field changes as it penetrates the coating. This helps determine how thick the coating is without damaging it. These gauges are commonly used in industries like manufacturing and automotive to ensure quality control and protect against corrosion by ensuring coatings are applied correctly.
