All-in-one Thickness Meter

The integrated thickness gauge measures the thickness of coatings or films by contacting the material surface with a probe, utilizing the principles of magnetic induction or eddy currents. The instrument converts signals into thickness readings, enabling rapid on-site inspection of non-conductive coatings on metal substrates or conductive layers on non-metallic substrates. It is suitable for coating quality inspection in industries such as automotive, shipbuilding, and steel structures.
Selection
When selecting, confirm the type of substrate material being measured. Use the magnetic induction principle for ferrous materials and the eddy current principle for non-ferrous materials. Choose the measurement range based on the coating thickness, with a common range of 0–2000 μm. Consider precision requirements; for general applications, ±1–3 μm is typical. Opt for a handheld device for portable use and a benchtop model for fixed workstations. Check whether the probe size is suitable for the curvature of the inspection surface. Verify that the instrument complies with national standards.
