PosiTest®

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.

Features

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)

Applications

Powder Coaters
Paint Applicators and Contractors
Coating Inspectors
Automotive Detailers, Refinishers and Inspectors

Technical Data

Specification	Details
Operating Temperature	–10 °C to +60 °C (gage and surface same temperature); surface can be –50 °C to +100 °C (defelsko.com)
Substrate Compatibility	Non-magnetic coatings on ferrous (steel) surfaces only
Calibration	Factory-calibrated; no drift thanks to rare-earth permanent magnet; long-form NIST/PTB certificate included
Intrinsic Safety	Fully mechanical—no electronic ignition source; suitable for hazardous areas
Durability	Corrosion-resistant brass body; can be immersed in fresh or salt water; rinse after saltwater use
Underwater Use	Yes—fresh and salt water operable, with proper cleaning after use
Substrate Surface Influence	Measures from effective magnetic surface; users should account for base-metal reading (BMR) on rough surfaces
