DeFelsko PosiTector 6000 FN1 All Metals Coating Thickness Gage (Standard Body, Integral FN Probe)
SKU: FN1-E
A rugged, one-handed coating thickness gage that automatically recognizes ferrous and non-ferrous substrates, measuring paint, powder, plating, galvanizing and more on all metals from 0 to 60 mils.

| 0–60 mils0 to 1500 µm range | Fe + NFeAuto substrate recognition | 60+Readings per minute | 2 yearsBody and probe warranty |
The DeFelsko PosiTector 6000 FN1 is a rugged, fully electronic coating thickness gage that uses magnetic induction and eddy current principles to measure coatings on both ferrous and non-ferrous metals, quickly and accurately. Its integral FN probe automatically recognizes the substrate and takes a measurement, making it ideal for steel, iron, aluminum, copper and mixed-metal work.
It's ready to measure right out of the box, with no calibration adjustment needed for most applications. The PosiTector Standard body stores 1,000 readings per probe, and the IP65 weatherproof enclosure and two-year warranty on body and probe make it the right choice for painters, platers, coaters and inspectors.
Key Features
![]() | One probe for all metalsThe FN probe automatically recognizes whether it's on a ferrous or non-ferrous substrate. It measures non-magnetic coatings on steel and iron with magnetic induction, and non-conductive coatings on aluminum, copper and other non-ferrous metals with eddy current. There's no need to switch probes when parts change. |
Fast, accurate and ready to measureTake more than 60 readings per minute, or over 90 in FAST mode for quick inspections. Built-in temperature compensation and a wear-resistant ruby probe tip keep readings accurate over time, and each gage includes a Long Form Certificate of Calibration traceable to NIST or PTB. | ![]() |
Built for the Field
Integral probe for one-handed use
The removable built-in FN probe has no cable, so you can measure with one hand. It can also be swapped for any other PosiTector 6000 probe, and each probe retains its own calibration information.
Statistics and memory
The Standard body stores 1,000 readings per probe, and Statistics mode continually displays the average, standard deviation, min/max and number of readings. Readings are accessible over USB like a flash drive, or through PosiSoft software for reports.
Flexible calibration
Choose from 1-point, 2-point, known thickness and average zero adjustment options. Hi-RES mode increases displayed resolution for precision work, and RESET instantly restores factory settings.
Rugged and weatherproof
The IP65 enclosure is weatherproof, dustproof and water-resistant, and resists solvents, acids, oil and water. A protective rubber holster with belt clip is included.
One body, many instruments
The PosiTector body accepts all PosiTector 6000, 200, RTR, SPG, DPM, IRT, SST, UTG, SHD, BHI and GLS probes, so it can become a surface profile gage, dew point meter, soluble salt tester, wall thickness gage, hardness tester or gloss meter.
