Ultrasonic Flaw Detector Portable NDT Tester For Weld & Material Inspection

This instrument is a portable industrial digital ultrasonic flaw detector that can quickly, easily, accurately and non‑destructively detect, locate, evaluate and diagnose various defects in workpieces, including cracks, inclusions, voids, and other discontinuities.

Suitable for both laboratory and on‑site engineering applications, it is widely used in manufacturing, iron and steel metallurgy, metal processing, chemical industry, and other fields requiring defect detection and quality control.

It also plays an important role in on‑line safety inspection and service life assessment in aerospace, railway transportation, boilers, pressure vessels, and related industries.

The instrument is widely applied to locate and size hidden cracks, voids, disbonds, and similar discontinuities in welds, forgings, billets, axles, shafts, tanks, pressure vessels, turbines, and structural components.

The instrument features core hardware based on ARM + FPGA architecture, paired with a highly reliable multi‑tasking operating system, greatly enhancing functionality, portability, durability and reliability.

It adopts a master‑slave menu structure with shortcut keys and a digital rotary knob. Lightweight and portable, it can be comfortably operated with one hand.

High‑resolution full‑digital multi‑color TFT LCD display (640×480 pixels) for clearer, more user‑friendly waveform presentation.

Four selectable user interface styles to adapt to different working environments.

60 Hz high‑speed refresh rate ensures clear display of subtle waveform changes. LCD brightness is fully adjustable.

All‑aluminum metal enclosure for excellent durability and strong electromagnetic shielding.

360° rotating damping stand and rubber boot for convenient operation. Tempered glass panel for superior hardness, wear resistance and scratch resistance.

Real‑time screenshot function for all interfaces and flaw detection screens, saved as BMP images to a USB flash drive in color or grayscale mode.

Flaw detection reports can be exported as PDF files to a USB drive for easy archiving and printing. All PDF content can be customized according to user requirements. BMP images and PDF files can be viewed on computers and mobile devices.
