Aluminum Foil Coating Thickness Gauge

The aluminum foil coating thickness gauge operates on the principle of eddy current or electromagnetic induction. The probe generates an alternating magnetic field, which induces eddy currents in the aluminum foil coating. By measuring changes in the magnetic field, the coating thickness is calculated. It is used to detect the thickness of coatings on aluminum foil surfaces, ensuring coating uniformity in industries such as food packaging and pharmaceutical packaging.
Selection
When selecting, consider that the measurement range should cover the sample thickness, and the eddy current principle is suitable for aluminum foil substrates. Confirm the instrument calibration method based on the coating type; handheld devices are suitable for on-site testing, while benchtop models are ideal for laboratory use. Check the instrument's error range and adaptability to sample curvature, and evaluate the impact of environmental temperature.
