Cabled FNDS Probe for Duplex Coatings

The PosiTector 6000 FNDS 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 gage 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 non-ferrous metal substrates.

Compatible with PosiTector Advanced (serial numbers 730,000+) and PosiTector Standard gage bodies with a color display. A Simple gage update may be required.
