Non-destructive testing(NDT) Equipments

coating thickness gauge

Core Advantages

  • Dual use for ferrous and non-ferrous metal substrate.
  • Digital probe can get stable data in repeated tests.
  • Responsive, fast measurement in 0.5s.
  • Ruby probe, longer service life.
  • Accurate data, ensure to pass the inspection of International Institute of Metrology.
  • Small and portable, single button, simple operation.

    • coating thickness gauge

  • The coating thickness gauge is used for detecting the coating thickness on metal surface.It adopts Hall effect and eddy current principles.It can be used to test the thickness of coatings, varnishes, enamels, etc.on ferromagnetic metal substrates such as steel.It can also be used to measure non-conductive coating thickness such as anodized coatings, ceramics on non-magnetic metal substrates such as copper, aluminum, die-cast zinc, brass, etc.
