Scanner finds the hole story.

The JF-15 High Speed Scanner is designed for NDT (Non-destructive Test) inspections of boltholes. When coupled with the UniWest US-454 EddyView instrument, cable and highly sensitive rotating probes the JF-15 scanner finds any indication of defect amplitude and/or circumferential location. A high scan rate of 1500 RPM assures full surface coverage at normal insertion rates. Minute flaws are easy to see on the full-colour screen of the US-454 EddyView instrument. One further feature is the system's portability, which makes it ideal for aerospace flightline applications.
