DISCONTINUED, We recommend the MiniTest 650N as a replacement

Measuring Range 0.1-40.0 mils (1-999 µm)

DCN-900 measures the thickness of paint coatings, anodize on aluminum, brass, zinc, stainless steel and other non-ferrous metals.


  • Dependable accuracy over the entire range of the gauge, not just at "calibration check" points.
  • Measures to 0.01 mil (0.1 µm), automatically rounding off to the nearest 0.1 mil (1 µm).
  • Keypad-selectable English or metric units.
  • Continuous reading update detects soft coatings as probe tip "sinks" into them.
  • The DCF-900 and DCN-900 include the gauge and probe, a bare test plate, two precision calibrations shims & instructions, all in a foam-fitted carrying
  • Calibration to NIST standards is available upon request.
  • Remote probe permits easy access for difficult, hard-to-reach places.
  • Longer lasting, driftless calibration... Set it and forget it for long periods of time and from job to job
  • Very reliable operation... Consistent, repeatable measurements.
  • Excellent results with thin substrates... As thin as 0.005" (10 µm)
  • Operation unaffected by magnetic fields
