Rough Surface Coating Thickness Gauge

The rough surface coating thickness gauge measures coating thickness on uneven surfaces using the principle of magnetic induction or eddy current. The probe contacts the coating, generating changes in the electromagnetic field, and calculates the thickness value at the interface between the substrate and the coating. It is used to detect the coverage thickness of paint or plating on rough surfaces such as castings and welds, ensuring uniformity of the coating.
Selection
When selecting, consider the substrate type to match the magnetic induction or eddy current probe, and ensure the roughness range covers the surface undulations of the sample. The measurement accuracy must meet the permissible process error, and the probe shape should adapt to curved surfaces or narrow gap inspections. The calibration method should support standard shims and zero-point calibration, and the instrument's protection rating should be suitable for the on-site environmental conditions.
