At present, the nondestructive testing of pipeline wall are based on the endoscope method, but generally two to three times the endoscope can only enlarge or does not have zoom function, to some suspicious signs of difficult observation and judgment, PTI-K200 (500) Comprehensive testing of pipeline came into being the instrument is a new type of detection equipment.From the principle that it is on a special feature of high-power electronic endoscope, but it can enlarge 200-500 times, and use of software can be observed the shortcomings of measurement (measuring system and image processing system highly integrated, easy to carry) . Also comes with high-brightness LED light, bright vision. The equipment has greatly enhanced the accuracy of detection of potential, but also improves work efficiency. It is very useful in the boiler, pipes, cylinders and other pressure vessels of NDT.
