Both methods are time consuming and error-prone . The PosiTector FNDS duplex probe performs this operation with one reading , simply and accurately .
DEFELSKO ' S SOLUTION
The PosiTector 6000 FNDS duplex coating thickness gage measures the individual thicknesses of both the paint and the zinc layers in a duplex coating system with a single reading .
In Duplex mode , the PosiTector 6000 FNDS utilises both magnetic ( ferrous ) and eddy current ( non-ferrous ) principles simultaneously to calculate and display the individual paint and zinc layer thicknesses .
The magnetic principle is used to measure the combined paint / zinc thickness over the ferrous substrate , and the eddy current principle is used to measure the paint thickness over the non-ferrous zinc coating .
The zinc thickness is calculated by subtracting the paint thickness from the combined paint / zinc thickness measurement .
When not in Duplex mode , the gauge will
operate like a conventional combination ferrous / non-ferrous instrument ( similar to PosiTector 6000 FNS probe ). Ideal for measuring non-magnetic coatings over steel and non-conductive coatings over nonferrous metal substrates .
