In practice
Where the DR130 is used
Check coating thickness on painted steel and aluminium bodywork, keep the readings in groups and compare them panel by panel. The DR130 runs on three AAA batteries and stores 2000 readings on the device.
01
Steel and aluminium panels
Automatic Fe/NFe
Magnetic induction for steel, eddy current for aluminium. The integrated alloy probe switches method automatically, so one gauge covers both panel types.
Minimum substrate thickness 0.4 mm; on curved areas the radius must be at least 5 mm convex or 25 mm concave.
02
Before and after refinishing
0–1500 μm
Read the coating build before and after paintwork so the thickness is recorded with the job, not judged by appearance alone.
Stated accuracy is ±(3% of H + 1.5 μm); readings depend on substrate, surface and measurement conditions.
