In practice
Where the DR280A is used
Run routine coating checks across steel and aluminium parts with one gauge. Magnetic induction and eddy current switch automatically, and the colour screen shows the reading where the work happens.
01
Steel and aluminium, one pass
Automatic Fe/NFe
Magnetic induction for steel, eddy current for aluminium. The gauge selects the method, so mixed-material inspection does not need a probe change.
Metal substrates only — not for coatings on plastic, wood or concrete.
02
Routine coating checks
0–1250 μm
Suits day-to-day coating control on painted, galvanised and finished metal parts across a 0–1250 μm range.
Minimum substrate thickness 0.4 mm, with a Φ16 mm minimum measurement area.
03
Rechargeable, colour screen
3.7 V 2000 mAh

μm · measuring range
Reading, group number and max / avg / min show on the 2.8-inch colour screen; the built-in 2000 mAh cell recharges for daily use.
Stated accuracy is ±(1%–3%)H + 1.5 μm; confirm suitability for the coating and substrate.
