Dual-Purpose Coating Thickness Gauge for Iron and Aluminum

The dual-purpose iron-aluminum coating thickness gauge utilizes magnetic induction and eddy current principles to measure the thickness of non-magnetic coatings on iron substrates and insulating coatings on aluminum substrates, respectively. It is used for rapid on-site inspection of coating and plating thickness on metal surfaces, and is applied in quality control across industries such as automotive, shipbuilding, and construction materials.
Selection
When selecting, consider matching the measurement principle to the base material type: use magnetic induction for iron-based materials and eddy current for aluminum-based materials. Ensure the measurement range covers common coating thicknesses, and the accuracy meets inspection standards. Choose a portable device suitable for on-site use, with probe sizes adaptable to different curved surfaces. Verify the instrument's calibration certificate and environmental impact compensation function.
