Plating Thickness Meter

Coating thickness gauges measure coating thickness using magnetic induction, eddy current, or ultrasonic principles. Magnetic induction is used for non-magnetic coatings on steel substrates, eddy current is suitable for insulating coatings on non-ferrous metal substrates, and ultrasonic methods can measure multi-layer structures. They are used for quality inspection, process control, and acceptance testing.
Selection
When selecting, ensure that the substrate type and coating properties match the measurement principle: use magnetic induction for ferrous substrates and eddy current for non-ferrous substrates. Consider the thickness range and accuracy requirements; use probe kits for rough surfaces. Verify the calibration capability with standard reference materials. Portable instruments are suitable for on-site use, while benchtop instruments are suitable for laboratory applications.
