Coating Thickness Gauges by Standard
When a coating-thickness purchase is driven by a written standard — ISO 19840 on structural steelwork, ISO 2808, SSPC-PA 2 or a method standard such as ASTM D7091 — the gauge has to match both the substrate the standard applies to and the calibration and reporting the standard expects. This guide groups the gauges by the kind of standard driving the work, so the shortlist already fits the document you report to.
1. Best Routes for Structural Steel and Protective Coatings Standards
Where the work is centred on protective coatings on steel structures, ferrous-capable instruments with a strong reporting workflow are usually the safest buying route.
- PosiTector 6000 GP is a strong standards-led route for protective coating work on steel, especially when reporting features matter.
- MiniTest 725 is a strong alternative when the workflow benefits from stored data and more advanced sensor handling.
- 3000FX series is the simpler route when a more compact standards-capable ferrous gauge is enough.
2. Best Routes for Magnetic and Eddy-Current Method Standards
If the governing requirement is fundamentally about the method family, the buying route should match the substrate first and then the workflow.
- PosiTector 6000 GP is a strong path for ferrous and mixed-substrate standards-led work.
- MikroTest remains relevant where a magnetic pull-off route is accepted and a mechanical instrument is preferred.
- PosiTector 6000 AN is a direct route for non-ferrous eddy-current work.
- MiniTest 745 is stronger when a more feature-rich non-ferrous workflow is needed.
- DCN-3000FX is the simpler non-ferrous route.
3. Best Routes When Dual-Substrate Standards Work Is Likely
- PosiTector 6000 GP is the strongest general route when standards-led work crosses both ferrous and non-ferrous substrates.
- DCFN-3000EZ is the wider-range budget route for dual-substrate work.
- PaintCheck is the simpler route when ease of use is more important than a more advanced feature set.

If the real issue is substrate and coating structure rather than formal standards, continue with Select a Coating Thickness Gauge by Substrate. If the main question is electromagnetic method family, use Magnetic vs Eddy Current Coating Thickness Gauge.
