Coating Thickness Meter for Steel Materials

Steel coating thickness gauges measure the thickness of coatings on steel surfaces through magnetic induction or eddy current principles. The magnetic induction method is used for non-magnetic coatings on steel substrates, while the eddy current method is suitable for insulating coatings on non-ferrous metal substrates. This instrument is used to detect the thickness of protective coatings, such as anti-corrosion paint and plating, ensuring that coating quality meets standards.
Selection
When selecting a steel coating thickness gauge, it is necessary to consider the type of substrate. For ferrous substrates, choose a magnetic induction type; for non-ferrous metals, opt for an eddy current type; and for mixed substrates, use a dual-function model. Select an appropriate measurement range based on the coating thickness, and pay attention to the instrument's accuracy and calibration certificate. Portable models are suitable for on-site inspections, and the shape of the probe should match the curvature of the surface being measured.
