As of mid 2021 the DCF-900 is no longer available. We recommend the MiniTest 650F as a replacement.

Measuring Range: 0-40.0 mils / 999 µm

The DCF-900 measures the thickness of paint, plating, coatings and galvanizing on iron or steel.


  • Dependable accuracy over the entire range
  • User selectable units (mils / microns)
  • Continuous reading update detects soft coatings as probe tip "sinks" into them.
  • NIST Traceable Calibration OPTIONAL ($100)
  • Remote probe permits easy access for difficult, hard-to-reach areas
  • Longer lasting, driftless calibration... Set it and forget it for long periods of time and from job to job
  • Excellent results with thin substrates... As thin as 0.005" (10 µm)
  • Supplied with bare test plate, two precision calibration shims & instructions, in a foam-fitted carrying case
