Lift-off Gauge

The lift-off thickness gauge measures coating thickness through magnetic induction or eddy current principles. The probe contacts the surface of the test object, utilizing differences in magnetic permeability or electrical conductivity between the substrate and the coating to calculate the thickness. It is used to detect non-conductive coatings such as paint and plastic on metal substrates, and monitors coating quality in automotive and furniture manufacturing.
Selection
When selecting a lift-off thickness gauges, it is necessary to confirm the substrate type (ferrous/non-ferrous) and match the probe principle (magnetic induction/eddy current). Consider whether the measurement range covers the expected thickness and ensure the probe shape adapts to the curvature of the surface being measured. Verify the instrument's calibration certificate and error range, and ensure the operating interface is simple and easy to read.
