In practice
Where the DR360A is used
Check galvanized and zinc coatings on ferrous steel, then convert the thickness reading into coating mass for the job record. The magnetic probe covers 0–2000 μm with a Φ11.5 mm minimum area.
01
Galvanized and zinc coatings
Magnetic induction
Measure zinc and galvanized coatings on steel parts, from thin passivation layers through to a 2000 μm range.
Ferrous substrates only — not for aluminium or other non-ferrous metals.
02
Thickness into coating mass
g/m² for the job record
Readings convert to coating mass per unit area, so an inspection can be recorded in the units your specification uses.
Coating mass is derived from measured thickness; confirm the conversion basis in the project specification.
03
Small parts, long shifts
3.7 V 3000 mAh
2000
μm · measuring range
A Φ11.5 mm minimum measurement area suits small stamped parts, and the 3000 mAh cell covers a working shift on one charge.
Minimum substrate thickness 0.3 mm; 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.
