Aluminum-based thickness Gauge

Aluminum-based thickness gauges utilize the eddy current induction principle to generate an electromagnetic field on the aluminum surface and measure changes in the induced current, thereby calculating the thickness of coatings or films on the substrate. They are used for thickness monitoring during surface treatment, spraying, anodizing, and other processes of aluminum products to ensure coating uniformity.
Selection
When selecting, consider that the measurement range covers the sample thickness, the probe size matches the test area, and the calibration method complies with industry standards. Pay attention to the influence of substrate curvature and surface roughness on readings, and prioritize models with temperature compensation functions to adapt to the workshop environment.
