MFD500B Portable Ultrasonic Flaw Detector adopts the international advanced IC technique and new-style color TFT LCD display. Its each performance index all arrive or even beyond international excellence. The instrument uses the artificial intelligence technology. It has very strong function and can be used very convenient. MFD500B can test, orient, evaluate and diagnose various flaws such as crack, lard, air hole in work piece's interior swiftly and accurately without any destruction. It can not only be used in lab but also can be used on engineering site. Also, it can be widely used for safety checking and life evaluating in fields of aeronautics, rail transportation and boiler pressure vessel.

KEY FEATURES
With English display, master-slave menu, shortcut key and digital swiftly knob, it's designed with leading technology and can be used very conveniently. With digital color TFT LCD display, it can choose the background color and wave color
According to the environment. And the LCD brightness also can be set freely by yourself. Designed with high performance securit guarantee battery module, its easy for disassembly and assembly. And it can charge independent with offline. And the large capacity and high performance Lithiuion battery module make the instrument' continuously working time to above 8 hours, with small size and light weight, the instrument can be hold by one hand. It's durable in use and lead industry trend.
