Iron-base Thickness Meter

The iron-based thickness gauge measures the thickness of non-magnetic coatings on ferromagnetic substrates using the principle of magnetic induction. The probe generates a magnetic field, and the coating thickness is calculated based on changes in magnetic resistance. It is used to detect the thickness of coatings such as paint, galvanized layers, and plastic coatings on steel surfaces, ensuring that the coating quality meets standards.
Selection
When selecting an iron-based thickness gauge, ensure the substrate is ferromagnetic metal and the measurement range covers the coating thickness to be tested. Consider the probe size for compatibility with the surface curvature, and ensure calibration sheets match the expected thickness. Pay attention to the instrument's temperature stability and verify compliance with industry testing standards. Portable instruments are suitable for on-site inspections, while fixed types are ideal for production lines.
