Rough Coating Thickness Gauge

A rough coating thickness gauge measures the thickness between the substrate and the coating interface using magnetic induction or eddy current principles, while combining probe contact with the surface to obtain roughness data. It is used to inspect the coating thickness and surface flatness in processes such as spraying and electroplating, ensuring that the coating quality meets production standards.
Selection
When selecting, consider the substrate type (magnetic induction for ferromagnetic materials, eddy current for non-ferromagnetic materials). The measurement range should cover the actual coating thickness, and the accuracy must match the process requirements. The probe size should be suitable for the shape of the workpiece, and calibration sheets must be consistent with the material being tested. Pay attention to the effects of temperature and humidity in the operating environment, and decide on the portability or fixed installation of the instrument based on site requirements.
