Certified Plastic Shims (foils) provide an economical alternative to coated metal plates. They have a reduced accuracy of ±2 µm (±0.08 mil). A coating thickness gage measures shim thickness when this shim is placed over a smooth metal surface.

Shims overview:

• Simulate a coating over a particular substrate material or shape. Gage performance can be conveniently verified on a regular basis as required by some international test methods
• For use with all Type 2, electronic coating thickness gages
• Protects the probe from damage or premature wear when placed over hot or abrasive surfaces
• Can be placed on top of soft or tacky coating films to obtain thickness measurements without the gage probe depressing the coating film
