						 (F type) Magnetic induction  | 
					
						 Can measure the thickness of non-magnetic coating layers on magnetic substrate  | 
					
						 Such as: (aluminum, chrome, copper, enamel, rubber, paint) on magnetic substrate (steel, iron, alloy and magnetic stainless steel)  | 
				
| 
						 (NF type) Eddy current  | 
					
						 Can measure the thickness of nonconductive coating layers covered on nonferrous substrate  | 
					
						 Such as: (enamel, rubber, paint, vanish, plastic anodic-oxide layer) covered on nonferrous substrate aluminum, brass, zinc, tin and nonmagnetic stainless steel)  |
