Multi-layer coating thickness Gauge

A multi-layer coating thickness gauge uses the principles of electromagnetic induction or eddy currents to perform non-destructive testing of the thickness of different coatings on a substrate. The probe emits signals that penetrate each coating layer, and the thickness is calculated layer by layer based on differences in electromagnetic properties. It is used for industrial quality inspections, such as automotive paint surfaces and electronic product coatings, to ensure that the coatings meet standards.
Selection
When selecting, consider the substrate type and coating material to match the measurement principle. Clearly define the number of coating layers and thickness range, and choose the corresponding probe. Check the instrument calibration certificate and error range. Pay attention to the influence of temperature and humidity in the operating environment. Portable devices are suitable for on-site testing, while benchtop models are suitable for fixed use in the laboratory.
