Through-coating memory-type thickness Gauge

The through-coating memory thickness gauge operates on the principle of magnetic induction or eddy current. The probe emits an electromagnetic field that penetrates the surface coating to reach the substrate. Based on changes in the magnetic field, the thickness of the substrate is calculated, and the data is stored. It is used to measure the true thickness of coated metal substrates and record measurements of multi-layer structures in on-site inspections in industries such as automotive and shipbuilding.
Selection
When selecting, confirm that the substrate type matches the principle of magnetic induction (ferrous) or eddy current (non-ferrous); the measurement range must cover the expected thickness; consider the maximum penetration capability of the coating; choose a model with memory if data storage is required; prioritize portable and shock-resistant designs for on-site use; and verify whether the probe size is suitable for measuring curved surfaces or narrow areas.
