Digital Dry Film Thickness Gauge

The digital dry film thickness gauge measures thickness by utilizing the principle of magnetic induction or eddy current, where the probe generates changes in the electromagnetic field upon contact with the coating. It is used to detect the thickness of non-conductive coatings such as paint and plastic on metal substrates, and to monitor coating quality in fields such as automotive painting and steel structure anti-corrosion.
Selection
When selecting, consider the substrate type: magnetic substrates use the magnetic induction principle, while non-ferrous metals use the eddy current principle. Choose the model based on the measurement range; for conventional coatings, select 0–2000 μm. Check the instrument's accuracy error value: ±1 μm for laboratory use and ±3 μm for on-site use. Calibration substrates and temperature compensation functions are required. Portable models are suitable for outdoor use, while fixed models are suitable for assembly lines.
