MFD500 Ultrasonic Flaw Detector
MFD500 Portable Ultrasonic Flaw Detector is utilized to detect & characterize internal defects in engineering materials such as metals, plastics & composites. High frequency ultrasonic waves locate voids, cracks & material discontinuities by producing distinct echo patterns.

• Master-slave menu, shortcut key and digital swiftly knob.
• Digital color TFT LCD display, background color and wave color are user   configurable. LCD brightness is adjustable.

• 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 detect 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 for tracking the time.
• USB 2.0 high speed communication port.
