Non-ferrous metal zinc coating thickness Gauge

Non-ferrous metal zinc coating thickness gauges measure the thickness of zinc layers using magnetic induction or eddy current principles. The magnetic induction method is used for steel substrates, where the magnetic resistance of the probe changes with the thickness of the zinc layer. The eddy current method is applied to non-ferrous substrates, where the alternating magnetic field of the probe generates eddy currents in the zinc layer, affecting the readings. These gauges are used for detecting the thickness of zinc coatings on galvanized sheets, fasteners, and other materials.
Selection
When selecting, confirm the substrate properties: use the magnetic induction principle for steel substrates and the eddy current principle for non-ferrous substrates. Consider matching the zinc coating thickness range with the instrument's measurement range. For on-site environments involving curved surface measurements, choose a small probe; for rough surfaces, use statistical mode. Calibration requires the use of standard foils or samples with known thickness.
