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.
- 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
