Detector adopt 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. UD-MFD**0 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 colors and wave color according to the
environment. And the LCD brightness also can be set freely by
you.
● Designed with high performance
security-guarantee battery module, it’s easy for disassembly and
assembly. And it can charge independent with offline. And the large
capacity and high performance Lithium-ion 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.
