| Operating principle | Application | For example |
| (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) |
