The Starrett 3813 is a state-of-the-art coating 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. The
3813 is ideal for a broad range of applications in manufacturing,
engineering and commercial inspection.
