The 3813 Coating Thickness Gage is a state-of-the-art coating thickness gage • Measuring range: 0-40mils (0-1000µm) max.
that utilizes the characteristics of both eddy current and magnetic induction to • Resolution: 0.1µm/0.1mils (0-99µm) or 1µm (over 100µm)
perform two types of thickness calculation. • Guaranteed tolerance (after one-point calibration):
The gage uses an integrated probe to automatically determine whether the ±1-3%n or 2µm (whichever is greater)
substrate is ferrous or non-ferrous. Then, it either detects the thickness of non- • 4-digit display, .40" (10mm) height,
