KEY FEATURES

MFD500 Portable Ultrasonic Flaw Detector with hi-resolution color TFT LCD display.
The background color and the wave color can be selectable according to the environment.
LCD brightness can be manually set. Continue working over 8 hours with high performance lithium-ion battery module ( with large capacity lithium-ion battery option) , easy to be dismantled and the battery module can be charged independently offline. It is light and portable, easily to be taken by one hand; easy operation; superior reliability makes it long life.

RANGE

0~ 9999mm ( at steel velocity) ; range selectable in fixed steps or continuously variable.

PULSER

Spike excitation with low, middle and high choices of the pulse energy.
Pulse Repetition Rate: manually adjustable from 10 to 1000 Hz.
Pulse width: Adjustable in a certain range to match different probes.
Damping: 100© , 200© , 400© selectable to meet different resolution and sensitivity need.
Probe work mode: Single element, dual element and through transmission;

RECEIVER

Real-time sampling at 160MHz high speed enough to record the defect information.
Rectification: Positive half wave, negative halfwave, full wave, and RF
:
DB Step: 0dB, 0.1 dB, 2dB, 6dB step value as well as auto-gain mode

ALARM

Alarm with sound and light, .

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.

REAL-TIME CLOCK

Real time clock for tracking the time.
