Ultrasonic Flaw Detector

Our company presents its full line of digital ultrasonic flaw detectors, coming with unmatched quality standards for indentifying discontinuities and other flaws. With a wide range of software options available for enhanced flaw detector inspection, these ultrasonic flaw detectors are the most suitable instruments appreciated by industry experts worldwide. These units offer improved LCD screen, USB interface, compact design and more economical price package.

Our ultrasonic Flaw Detectors come in both digital and analog models where digital ultrasonic flaw detectors comprise of an ultrasonic pulser / receiver, hardware and software for signal capture and analysis, a waveform display, and a data logging module and analog flaw detectors are still manufactured, most contemporary instruments use digital signal processing for improved stability and precision.


Both the DAC and the AVG method of amplitude evaluation are available Semiautomatic two point calibration
Curved Surface Correction feature Suitable for use on large work pieces
Automatic display of precise flaw location Automatic gain control, peak hold and peak memory
Data can be printed or saved for record purpose Screen scenes can be captured as movie files
