Specification :

Portable Ultrasonic Flaw Detector MFD500MFD500 Portable Ultrasonic Flaw Detector adopte 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 use the artificial intelligence technology. It has very strong function and can be used very convenient. MFD500 can test, orient, evaluate and diagnose various flaws such as crack, lard, air hole in worklpiece’ 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.

MERMORY
Total 100 configuration channels store all instrument operating parameters plus DAC/ AVG curve; stored configuration data can be easily previewed and recalled for quick, repeatable instrument setup. Total 1000 datasets store all instrument operating parameters plus A-scan. All the configuration channels and datasets can be transferred to PC via USB port.
FUNCTIONS
Peak Hold:
Automatically searching the peak wave inside the gate and hold it on the display.
Equivalent diameter calculation: find out the peak echo and calculate its equivalent diameter.
Continuous Record: Record the display continuously and save it to the memory inside the instrument.
Defect Localization: Localize the defect position, including the distance, the depth and its plane projection distance.
Defect Sizing: calculate the defect size
Defect Evaluation: Evaluate the defect by echo envelope

DAC: Distance Amplitude Correction
AVG: Distance Gain Size curve function
Crack measure: Measure and calculate the crack depth
B-SCAN: Display the cross-section of the test block.
