DeFelsko PosiTector 6000 FS1 Ferrous Coating Thickness Gage (Standard Body, Cabled FS Probe)
SKU: FS1
A rugged coating thickness gage with a waterproof stainless steel cabled probe for measuring non-magnetic coatings on steel and iron from 0 to 60 mils, ideal for hard-to-reach areas and underwater use.

The DeFelsko PosiTector 6000 FS1 is a rugged, fully electronic coating thickness gage that uses the magnetic induction principle to measure non-magnetic coatings on steel and iron quickly and accurately. It pairs the PosiTector Standard body with the FS regular cabled probe, a constant-pressure stainless steel probe that is hermetically sealed and totally waterproof.
The cable lets you reach into tight spots, measure at arm's length and even take readings underwater, while the gage body stays dry and readable. It's ready to measure right out of the box for most applications, and backed by a two-year warranty on body and probe.
Key Features
![]() | Waterproof cabled probeThe constant-pressure stainless steel FS probe is hermetically sealed and totally waterproof, making it ideal for underwater use and wet environments. Its cable gives flexible access to curved surfaces, confined areas and complex part shapes where a built-in probe is hard to position. |
Built for the Field
Made for coatings on steel
Measure paint, powder, plastic, enamel, galvanizing and plating on steel and iron. Take more than 60 readings per minute, or over 90 in FAST mode, with built-in temperature compensation.
Ready to measure, accurate for years
No calibration adjustment is required for most applications, and each gage includes a Long Form Certificate of Calibration traceable to NIST or PTB.
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, and RESET instantly restores factory settings.
Rugged, interchangeable platform
The IP65 body is weatherproof, dustproof and water-resistant. Each probe retains its own calibration, so the body accepts any PosiTector 6000, UTG, SPG, DPM and other PosiTector probes.
