Description

MFD**0B Portable Digital Ultrasonic Flaw Detector is a economical and practical model improved on MFD**0. Except for the differences of its measuring range, working frequency and transmitted pulse parameter, the other performances are the same as MFD**0. Based on ultrasonic pulse reflection testing principle, MFD**0 controls all testing process by the mini-processor. And it has low power design and can do charge with two models such as online charging 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, MFD**0 is one of our company’s high promoted super cost performance and economically ultrasonic flaw detector.

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.
