Coating Thickness Base Substrate	Probes	Measuring Range	Applications
Non-Ferrous	FTA3.3H View Details	0–1200 µ (0–47.24 mils)	Coating thickness on non-ferrous metal base materials (NF); NC/NF.
	FTA3.3FG View Details	0–1200 µ (0–47.24 mils)	Measures non-conductive coatings on non-ferromagnetic metals (Iso/NF); moisture-sealed probe—ideal for anodized layers with acidic contamination.
	FAW3.3 View Details	0–1200 µ (0–47.24 mils)	Measures non-conductive coatings on non-ferromagnetic metals, works well in flat areas or recesses, and may also function on slightly damp or contaminated surfaces.
	FAI3.3-150 View Details	0–800 µ (0–31.49 mils)	Measuring the thickness of electrical non-conducting coatings on non-ferromagnetic metal base materials (NC/NF).
Ferrous	D-F (FGAB1.3) View Details	0–2000 µ (0–78.74 mils)	Measures the thickness of electrically non-conductive and non-ferromagnetic metallic coatings on steel or iron (Fe) base materials.
	FGAB1.3-150 View Details	0–1000 µ (0–39.37 mils)	Measures non-conductive and non-ferrous coatings on steel/iron; ideal for bores, pipes, and grooves; external-triggered low-uncertainty on IDs ≥ 11.5 mm (0.45 in).
	D-F-Ro (F20H) View Details	0–2500 µ (0–98.43 mils)	Measures electrically non-conductive and non-ferromagnetic metallic coatings on steel or iron (Fe) base materials.
	FGABW1.3 View Details	0–2000 µ (0–78.74 mils)	Measures non-conductive and non-ferrous metal coatings on steel or iron, including in pipes and recesses, but may require special probes for accurate results on rough surfaces.
Ferrous / Non-Ferrous	D-FN (FD13H) View Details	0–2000 µ (0–78.74 mils)	Dual-method probes measure coating thickness on both ferrous and non-ferrous metals and are well-suited for rough surfaces due to their large pole tip.
