The PenTest is manufactured by Elektrophysik, Germany. The PenTest measures the Non Destructive measurement of non-magnetic coatings, e. g. paint, enamel, rubber, chrome on steel.



The PenTest magnets, spring mechanism and casing are designed for durability and a long service life. Measurement is taken by sliding a plastic ring manually so the PenTest does not require batteries.


For the non-destructive measurement of:

  • Non-magnetic coatings, e. g. varnishes, paint, enamel, rubber, chromium and zinc on ferromgnetic based materials e.g. steel.
  • Performance features: – Non-wearing permanent magnet.
  • Measuring without power supply.
  • No calibration required.
  • Measurement at any angle.
  • Measurement value hold for exact readings.
  • Measuring principle – Magnetic attraction principle.


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