Application of ultrasonic flaw detector : 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, it can used to 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 is widely used for flaw detecting in fields of power engineering , boiler pressure vessel , Steel Construction , war industry , aeronautics , rail transportation ,auto and machinery etc. It is the essential flaw detecting instruments in NDT industry.
MFD350B Portable Digital Ultrasonic Flaw Detector is a economical and practical model improved on MFD500B. Except for the differences of its measuring range, working frequency and transmitted pulse parameter, the other performances are the same as MFD500B.
Based on ultrasonic pulse reflection testing principle, MFD350B controls all testing process by the mini-processor. And it has low power design and can do charge with two models such as online chargeing and offline charging. And it can work continuously about 8 hours.With large capacity, digital multi-color TFT LCD, original imported stable IC, small size, light weight, stable performance and favorable price, MFD350B is one of our company’s high promoted super cost performance and economically ultrasonic flaw detector.
With 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 colour and wave color acoording to the environment. And the LCD brightness also can be set freely by yourself.
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’ continously 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.
