Coating Thickness Gauge MiniTest 4100

Examples of use:

  • Non-destructive coating thickness measurement
  • Measurement of:
    • Non-magnetic coatings (e.g. paint, zinc etc.) on iron and steel (no austenite)
    • Insulating coatings (e.g. paint, anodising coatings) on non-ferrous metals and austenitic steels
    • Non-ferrous metal coatings in insulating substrates

Device configuration:

  • Magnetic induction principle for measuring on steel (F-probes)
  • Eddy current principle for measuring on non-ferrous metals (N-probes)
  • Measuring range 0–2000 µm depending on connected probe and measuring task
  • Flat measuring surface with minimum 10x10 mm
