NEW TITLE HERE

DeFelsko PosiTector FNDS Cabled Probe measures the individual thicknesses of both the paint and the zinc layers in a duplex coating system with a single reading. Duplex coating systems use a combination of two corrosion protection systems – typically paint or powder coating over galvanized steel (hot-dip, electro, or zinc spray metallizing). The resultant corrosion protection is superior to either protection system used independently.

In Duplex mode, the PosiTector 6000 FNDS utilizes 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 disabled, the gauge will operate like a conventional combination ferrous/non-ferrous instrument (similar to PosiTector FNS probe). Ideal for measuring non-magnetic coatings over steel and non-conductive coatings over non-ferrous metal substrates.
