Coating Thickness Meter for Non-metallic Base Layers

Non-metallic substrate coating thickness gauges operate based on the principles of eddy current or electromagnetic induction. The probe generates an alternating magnetic field, which induces eddy currents in the conductive coating. The thickness is calculated by measuring changes in the magnetic field. These gauges are used to measure the thickness of metal coatings on non-metallic substrates, commonly applied in industrial quality inspections such as electroplated layers on plastic parts and copper foil on printed circuit boards.
Selection
When selecting, consider the substrate type and flatness, as the conductivity of the coating determines whether to use eddy current or electromagnetic principles. The measurement range must cover the actual coating thickness, and the precision should meet the process requirements. The probe size should accommodate the shape of the measured object, and the calibration standard sheet material must match the measured coating. The instrument's ease of operation, data storage function, and environmental adaptability should be configured as needed.
