Magnetic Coating Thickness Gages for Non-Magnetic Coatings on Steel

PosiTest magnetic pull-off thickness gage (banana gauge) for the non-destructive measurement of non-magnetic coatings (paint, enamel, galvanizing, metalizing, plating, etc.) on steel.


  • Highly wear resistant Carbide Probe for longest life and continuous accuracy
  • Extra rugged housing, not affected by mechanical shock, water, acid or solvents
  • Unique overall design, fully supported, positive positioning, no pivoting tendencies during measurement
  • Positive visual and audible indicators to designate when thickness reading is established
  • “V” grooves in probe housing and gage base allow correct positioning on cylindrical objects
  • Certificate of Calibration showing traceability to PTB included (Long Form)


Conforms to ASTM D7091/B499, ISO 2808 and others



Hot dip galvanizing, hard chrome metalizing, paint, enamel, plastic coatings on steel.



0-2000 µm



±5 µm up to 100 µm
±5% of the reading over 100 µm
