3813 Coating Thickness Gage 69883

3813 Coating Thickness Gage
Coating Thickness Gage, 0-40mils/0-1000 um, +/- 1-3%n or 2 um, 302 F

Coating Thickness Gage is state-of-the-art thickness gage that utilizes the characteristics of both eddy current and magnetic induction to perform two types of thickness calculation. The gage uses an integrated probe to automatically determine whether the substrate is ferrous or non-ferrous, then it either detects the thickness of non-magnetic coating on a magnetic substrate (ferrous) or the insulating coating on a non-magnetic conductive substrate (nonferrous). Testing performance is non-destructive and extremely accurate. Ideal for a broad range of applications in manufacturing, engineering and commercial inspection.
