FIELD: instrument engineering.
SUBSTANCE: system can be used for finding defects in pipelines. System has reducer, which has four light-emitting diodes and integrates with breechbush of item by means of cone and releasing levers. System also has optical unit with mirror assembly, TV camera and measuring head entering carrier-pickup. Carrier-pickup is located in shaft pipe in such a way to make light-emitting diodes forming three concentric circles with center disposed at optical axis of shaft pipe.
EFFECT: widened operational capabilities.
