PosiTector 6000FNDS Duplex Coating Systems Gauge

Made in the USAWith a single reading the PosiTector 6000 FNDS probe measures the individual thicknesses of both the zinc and the paint layers in a duplex coating system (with a minimum zinc layer thickness of 13µm).

The PosiTector 6000 FNDS probe is designed to measure individual layer thicknesses of zinc and paint/powder in a duplex coating system

The Zinc layer can be applied using several methods:

  • Hot-dip galvanizing (most common for duplex coatings) 
  • Electro-galvanizing 
  • Zinc spray metallizing (thermal spray zinc)


Two corrosion protection methods are better than one. That's the theory behind the Duplex Coating Systems, which combine the protection of galvanization with the benefits of an additional corrosion protection system, such as polymeric powder coating or paint.

The result of using a combination of two protection methods is often better than the result of the individual protection method used independently.

The PosiTector 6000 FNDS (in duplex mode) 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 zinc/paint 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 zinc/paint thickness measurement. 

The 6000 FNDS probe is compatible with all PosiTector Advanced and Standard models with a color display.

The PosiTector 6000 FNDS can also be taken out of ‘Duplex Mode’, allowing it to act as a PosiTector 6000 FNS probe to measure: 

  • Non-magnetic coatings on ferrous metals (steel) 
  • Non-conductive coatings on non-ferrous metals
