Smart Paint Film Thickness Gauge

The intelligent paint film thickness gauge measures coating thickness non-destructively through magnetic induction or eddy current principles. The probe contacts the surface, generating changes in the electromagnetic field to calculate film thickness data, which is automatically stored and transmitted. It is used for on-site inspection of coating quality in applications such as automobiles, ships, and steel structures.
Selection
When selecting, consider the substrate type corresponding to the principles of magnetic induction or eddy current, ensuring the measurement range covers the coating thickness to be tested. Pay attention to matching the probe size with the curvature of the measurement area, and check the instrument's calibration certificate and error values. Opt for data export functionality if needed.
