The DeFelsko PosiTector 6000 FN3 pairs the integral FN all-metals probe with the PosiTector Advanced gage body. The probe uses magnetic induction and eddy current principles and automatically recognizes the substrate, measuring coatings on steel, iron, aluminum, copper and more, quickly and accurately.
The Advanced body adds everything professional inspectors need to document their work: memory for 250,000 readings in up to 1,000 batches, WiFi and Bluetooth connectivity, three scan modes, live graphing and onscreen batch notes. It's housed in an IP65 weatherproof enclosure and backed by a two-year warranty on body and probe.
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. |
Advanced data and wireless connectivityStore 250,000 readings in up to 1,000 batches. WiFi synchronizes with PosiSoft.net and downloads software updates, and Bluetooth 4.0 sends data to the PosiTector App on iOS or Android or to an optional portable printer. USB Keyboard mode and live streaming feed readings straight into PCs and third-party software. | ![]() |
Built for the Field
Fast readings and scan modes
Take more than 60 readings per minute, or over 90 in FAST mode. Three scan modes let you take over 180 readings per minute without lifting the probe, which is ideal for large surfaces.
Live graphing and batch notes
Watch measurement data graphed live on screen, and use the built-in QWERTY keyboard to rename batches and add notes while you inspect.
Ready to measure, accurate for years
No calibration adjustment is required for most applications. Built-in temperature compensation and a wear-resistant ruby probe tip keep readings accurate, and each gage includes a Long Form Certificate of Calibration traceable to NIST or PTB.
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.
