Description
Certified Precision Plastic Shim (set of 8) for PosiTector Ultrasonic Paint Thickness Gages. 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 (zero plate).
