In practice

Where the DR380A is used

Cover thick and thin coating builds on steel and aluminium with one gauge. Automatic Fe/NFe switching handles mixed-material inspection, and the 2000 μm range keeps headroom for heavy coatings.

DR380A dual-mode coating thickness gauge with probe

01

Steel and aluminium, automatic

Fe/NFe switching

Magnetic induction for steel, eddy current for aluminium. The gauge selects the method, so a mixed-material line needs one instrument, not two.

Metal substrates only — not for coatings on plastic, wood or concrete.

02

Headroom for heavy builds

0–2000 μm

2000 μm of range covers primer through thick protective systems, with a 0.3 mm minimum substrate thickness.

Stated accuracy is ±(1%–3%)H + 1.5 μm.

03

All-shift power

3.7 V 3000 mAh

2000

μm · measuring range

The 3000 mAh cell and 2.8-inch colour screen suit full-shift line inspection; a Φ16 mm minimum area fits most formed parts.

At curved parts the radius must be at least 5 mm convex or 25 mm concave.
