Technical Description

The LTI-6200 is a compact, portable thermal shearography system designed for the nondestructive inspection of aerospace composite repairs, structures and components.The LTI-6200 has a vacuum attach feature to allow operation in any orientation on-aircraft, on panels in the shop or on the bench. The patented cantilevered design allows inspection up to edges and corners on flaps, control surfaces, wing panels or cut-outs. The system features automatic operation with easily SAVE/RECALL NDE Procedure Macros, automatic exposure and image storage. The LTI-6200 includes the Inspection Head, Controller, cable set and transit case.
