Magnetic Paint Thickness Gauge

The magnetic paint thickness gauge operates on the principle of magnetic induction, where the change in magnetic flux when the probe contacts the coating reflects the thickness. It is used to measure the thickness of non-magnetic coatings on steel substrates and is applied in on-site inspections of coating uniformity in industries such as automotive and shipbuilding.
Selection
When selecting, consider matching the probe type to the substrate shape: use a single probe for flat surfaces and a dual probe for curved surfaces. Ensure the measurement range covers the thickness of the coating to be tested, and the environmental temperature suits the working conditions. Verify the instrument's calibration certificate and error range.
