Digital Ultrasonic flaw detector for NDT
Portable Ultrasonic Flaw Detector
Overview
Portable Digital Ultrasonic Flaw Detector is a economical and practical model . Except for the differences of its measuring range, working frequency and transmitted pulse parameter, the other performances are the same
Based on ultrasonic pulse reflection testing principle, 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, SUB100 is one of our company's high promoted super cost performance and economically ultrasonic flaw detector.

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.
