Crack Depth Meters

The Karl Deutsch RMG 4015 uses the potential drop (four-point) method to determine surface crack depth of 0–99.9 mm in steel and 0–12 mm in aluminium, copper and brass, as well as the direction of inclined cracks. A pocket-size instrument with data logger, RS232 interface and straight, angled and inclined-crack probes – it complements MT and PT inspection when you need to assess whether a defect can be removed by grinding.
