Non-destructive metal coating thickness Gauge

Non-destructive metal coating thickness gauges measure the thickness of non-conductive/conductive coatings on metal substrates through magnetic induction or eddy current principles. The probe generates an electromagnetic field, and variations in coating thickness cause changes in the magnetic field intensity, which the instrument uses to calculate the thickness value. It is used to inspect the thickness of metal surface treatment layers, such as electroplating and spraying, ensuring products meet specification requirements.
Selection
When selecting, confirm that the substrate type (ferromagnetic or non-ferromagnetic) matches the measurement principle, taking into account the characteristics of the coating material. Choose the probe size based on the shape of the workpiece, with dedicated probes required for curved surfaces. Clarify the thickness range and accuracy requirements, and pay attention to the temperature, humidity, and protection level of the on-site environment. Verify the instrument calibration certificate and compliance with industry standards.
