PosiTector 6000 FNDS Duplex Coatings Probe
Article No. 15273
Probe FNDS, Regular Cable, 0-60 mil
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.
Features
- Helps in corrosion protection - 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.
- FNDS probe 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 paint/zinc thickness over the ferrous substrate
- 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.
