ElektroPhysik MiniTest 650 Coating Thickness Gauge

NDT Equipment Sales


The MiniTest 650 Coating Thickness Gauge is a rugged gauge with fixed external probe for all non-magnetic coatings on steel and all insulating coatings on non-ferrous metals.

Particularly suited to measure coating thickness in rough environments and on abrasive surfaces, e.g. sand-blasted steel, heavy duty corrosion protection in ship building, at offshore installations and mining facilities, on plasma-sprayed surfaces.

The MiniTest 650 is successor to the MiniTest 600 tried and tested over many years. For measurement on rough steel surfaces, for e.g. in shipyards, it comes with a special wear-resistant F probe and thus enables long-term use.


Non-destructive coating thickness measurement:

  • Non-magnetic coatings such as varnishes, enamels, chrome and zinc on ferromagnetic base materials (e.g. steel)
  • Insulating coatings like varnishes and anodizing aluminium on non-ferrous metals (e.g. aluminium, copper, die-cast zinc).


  • Coating thickness measurement of up to 2 and 3 mm.
  • Universal probe offering automatic substrate identification for quick measurement on steel and non-ferrous metals.
  • Wear-resistant probe tips with practically unlimited durability.
  • USB-interface to transfer data to a PC.
  • Statistical evaluation of the readings (measurement data).
