The Positest coating thickness gauge is designed for the non-destructive measurement of nonmagnetic coatings such as (paint, enamel, plastic, galvanizing, metalizing, plating, etc.) on STEEL. Easily measures small parts of almost any shape. Stable design with additional tail-end support. No annoying rocking during measurement.


  • Permanently calibrated
  • “V” grooves in probe housing and Gage base allow correct positioning on cylindrical objects
  • Highly wear resistant Carbide Probe for longest life and continuous accuracy
  • Can be used underwater
  • Extra rugged housing, not affected by mechanical shock, water, acid or solvents
  • GO/NO-GO button can be pre-set for rapid measurement
  • Explosion Proof – Refinery safe
  • Made in the USA
  • Supplied with NIST Traceable Calibration Certificate
