[0002] The channel radiographic flaw detector is a multi-channel, distributed precision testing instrument. It utilizes internationally advanced integrated circuit and network technologies to quickly, conveniently, non-destructively, and accurately detect, locate, evaluate, and diagnose a variety of defects within workpieces. It is widely used in manufacturing, steel and metallurgy, metalworking, rails, steel pipes, and plate industries.
