DIGITAL ULTRASONIC FLAW DETECTOR
MAKE DINESH SCIENTIFIC
MODEL DS-DUFD-100
DESCRIPTION
A Digital Ultrasonic Flaw Detector is a non-destructive testing (NDT) device designed to detect, characterize, and evaluate flaws or discontinuities in various materials such as metals, plastics, and ceramics. It uses high-frequency sound waves (ultrasound) to detect internal flaws without damaging the test object, which makes it essential in industries like aerospace, automotive, manufacturing, and construction.

Key Features of a Digital Ultrasonic Flaw Detector:
 Digital Display and Processing: Provides a clear, high-resolution digital display for viewing ultrasonic waveforms, making analysis easier and more accurate.
 High Sensitivity: Capable of detecting small flaws at various depths, ensuring thorough inspection.
 Portable and Lightweight: Often designed to be handheld or portable for use in field inspections and confined spaces.
 Data Storage and Transfer: Enables storage of inspection data and often includes USB or wireless options for transferring data to computers for further analysis.
 Adjustable Parameters: Allows users to adjust settings like frequency, gain, and pulse width to optimize detection based on material properties.
