Metal Substrate Film Thickness Meter

The metal substrate thickness gauge operates based on the principles of magnetic induction or eddy currents. The probe contacts the metal surface to generate an electromagnetic field, and the thickness of the coating is calculated based on changes in the magnetic field. It is used to measure the thickness of coatings or platings on metal substrates and is widely applied in quality inspections in industries such as automotive and home appliances.
Selection
When selecting, consider the compatibility between the substrate type and the measurement principle based on coating properties: use magnetic induction for ferrous substrates and eddy current for non-ferrous substrates. Ensure the measurement range covers the sample thickness and the accuracy meets the process requirements. The probe size should be suitable for the shape of the inspection area, and the instrument must come with a calibration certificate.
