3813
Coating Thickness Gage
|
|
Automatically Detects Ferrous or Non-Ferrous Substrate
|
|
|
|
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 (non-ferrous).
|
|
|
|
Testing
performance is non-destructive and extremely accurate. The 3813 is ideal for
a broad range
|
|
of applications
in manufacturing, engineering and commercial inspection.
