Mini-Probe for Access to Hard-to-Reach Areas

Insert the 1/8-inch Mini-Probe in tiny, hard-to-access places, such as pipes, tubes, aircraft engines, and aircraft wings. A fiber optic cable carries the signal to a photomultiplier tube.

... Inserting the mini-probe inside the pipe means x-rays only have to travel through one wall, so the defect appears clearly (see below).
