Coating Thickness Meter CM-8822,coating thickness tester,Ultrasonic thickness gauge, thickness meters, thickness gauge

Coating thickness meter is widely used for measuring thickness and corrosion of pressure vessels,chemical equipment,boilers,oil storage tanks,etc.In industries of petroleum,shipbuilding,power station,and machine manufacturing.

Operating principle:  F type & NF type
F type(magnetic induction): measure the thickness of non-magnetic coating layers such as(aluminum,chrome,copper,ename1,rubber,paint) on magnetic substrate (steel, iron, alloy and magnetic steel) 
NF type (eddy current): measure the thickness of non-conductive coating layers (ename1, rubber, paint, vanish, plastic anodic oxide layer) covered on non-ferrous substrate (aluminum, brass, zinc, tin and non-magnetic stainless steel)
