The standard of the industry (ASTM D-4166)

Accurate thickness measurement in inches & metric on your FRP (GRP) laminates and linings. Measure thickness of any nonmagnetic materials such as rubber, lead, wood, polyester, aluminium, etc.

Laminates capacity 1.2" (31.75mm)
Linings capacity 0.5" (12.7mm)

The most indispensable instrument ever devised for the non-destructive thickness measurement of nonmagnetic materials

COMPARE THESE ABILITIES :

1. Is not influenced by varying densities (composites), air voids, delaminations or foreign inclusions
2. Will measure any non-magnetic material, non-destructively
3. Direct read-out in inches and metric
4. Automatic magnet finding and centering ability
5. Low battery indicator
6. Simple rapid calibration
7. Powered by 2 standard 9volt transistor batteries
