PosiTest Coating Thickness Gauge by DeFelsko

PosiTest Coating Thickness Gauge by DeFelsko is an easy-to-use magnetic pull-off gauge for measuring cured coatings on steel. PosiTest is explosion proof, making it safe for use in refineries and similar applications.

The PosiTest coating thickness gauge offers a dial indicator in mils or microns, with scales for thinner non-magnetic coatings like galvanizing, or thicker coatings up to 80 mils on steel. PosiTest features a rugged housing that is impact, water, acid, and solvent-resistent. V-grooves on the probe end permit measurement of coatings on cylindrical objects. PosiTest is light-weight and compact, and balanced so that it works in any position.



PosiTest features:

  • wear-resistant carbide probe for long life and continuous accuracy
  • easy calibration adjustment
  • housing not affected by mechanical shock, water, acid or solvents
  • design ensures instrument stability for reliable readings
  • explosion proof and refinery safe
  • visual and audible indicators when reading is established
  • compact, lightweight, precisely-balanced independent of gravity - can be used in any position
  • go/no-go button can be pre-set for rapid measurement
  • one-finger operation
  • comes with wrist strap, neck strap, and instructions, in a quality leather case with belt loops

PosiTest is available in four scales:

  • PosiTest FM: 0 - 80 mils; tolerance of +/- 0.2 mils to 4 mils, +/- 5% of reading over 4 mils
  • PosiTest F: 0 - 2000 microns; tolerance of +/- 5 microns up to 100 microns, +/- 5% of reading over 100 microns
  • PosiTest GM: 0 - 8 mils; tolerance +/- .04 mils up to .8 mils, +/- 5% of reading over .8 mils
  • PosiTest G: 0 - 200 microns; tolerance +/- 1 micron up to 20 microns, +/- 5% of reading over 20 microns
