Small-line portable electronic pipe endoscope is a new type of instrument which integrates optics, precision machinery, electronic technology and micro-camera technology to inspect the internal welding quality of the cavity, nondestructive testing and search and rescue. It uses high-strength elastic fiber cable, the dozens of-metre-long cable reel can be inserted and retracted very freely in the line its most notable feature is its portability, which is especially suitable for situations where there is no AC and no platform to climb, and its probes can reach the toxic, harmful, and space-tight parts of routine testing that cannot be reached. A highly integrated, lightweight, high-energy lithium-ion battery is designed to greatly improve the performance of mobile portability compared to ordinary endoscopes. It can clearly show the location of the image, check the whole process can be photographed, video, data stored in a random SD card, left the scene can be connected by USB interface or card reader and computer, can be very convenient to archive and analyze the data.
