Magnetic coating thickness gauge PenTest

The PenTest is a sturdy coating thickness gauge in the form of a pen, which measures the thickness of non-magnetic coatings on steel, based on the magnetic attraction principle; measuring range 25 – 700 µm.

The magnets, spring mechanism and casing are designed for durability and a long service life.

Measurement is taken by sliding a plastic ring manually and thus does not require batteries.


Non-destructive measurement of:

  • Non-magnetic coatings like varnishes, enamels, chromium and zinc on ferromagnetic base materials (e.g. steel)


  • Strong stainless steel casing
  • Permanent magnet made by an unique ElektroPhysik manufacturing process
  • Measuring range 25 – 700 µm
  • Battery-free operation
