In practice
Where the DR3000 is used
A one-piece gauge for industrial coating checks on steel and aluminium. The integrated probe needs no cable, and 3000 μm of range lets thin paint and heavy builds share one instrument.
01
One-piece probe, no cable
Integrated alloy probe
The probe is built into the housing, so there is no cable to manage on a ladder or under a vehicle: press and read.
Metal substrates only — not for coatings on plastic, concrete or wood.
02
3000 μm on one gauge
0–3000 μm
Magnetic and eddy current in one instrument, with a range to 3000 μm so thin paint and heavy builds share a single gauge.
Stated accuracy is ±3% of H + 2 μm.
03
Light body, field power
106 g · 3 × AAA
3000
μm · measuring range
A 106 g body and a backlit 2.3-inch display suit long inspection rounds; power comes from three AAA cells.
Minimum substrate 0.4 mm; at curved parts the radius must be at least 5 mm convex or 25 mm concave.
