The Probe of Coating Thickness Gauge

technical parameters

    F-use magnetic probe, based on measurable magnetic metal (such as steel, iron, steel alloys and hard-magnetic, etc.) on non-magnetic coating thickness (such as zinc, aluminum, chromium, copper, rubber, paint, etc.). 
N-type probe use of eddy current way, measurable magnetic non-ferrous metal matrix (such as copper, aluminum, zinc, tin, etc.) and non-conductive, Austenitic stainless steel cover the thickness (such as: rubber, paints, plastics, anodizing film ). 
F / N-probe (except N400) gage with the times and can be used, other brands gage would need change.
