In practice
Everyday coating checks on painted and galvanised steel parts, with readings that convert to coating mass for the job record. The magnetic probe covers 0–1250 μm on a small Φ11.5 mm spot.

01
Magnetic induction
Handle routine coating control in industrial finishing and metal fabrication on ferrous parts, across a 0–1250 μm range.
Ferrous substrates only — not for aluminium or other non-ferrous metals.
02
Thickness to coating mass
Galvanised readings convert to coating mass per unit area, so an inspection can be recorded in the units the specification uses.
Coating mass is derived from measured thickness; confirm the conversion basis.

μm · measuring range
A Φ11.5 mm measurement spot suits small formed parts, and the 2000 mAh cell recharges between inspection rounds.
Stated accuracy is ±(1%–3%)H + 1.5 μm; at curved parts the radius must be at least 5 mm convex or 25 mm concave.
Where it stopsFerrous metal substrates only. Not for non-ferrous metals, and not for coatings on plastic or concrete. Coating mass is a conversion from measured thickness, not a direct reading.
