Affordable Flaw Detectors for Ultrasonic Testing, Thickness, and Sound Velocity

Handheld ultrasonic flaw detectors are versatile instruments that can be used to detect and assess defects, perform thickness measurements, and evaluate the sound velocity of different materials. They are widely used across multiple industries—nuclear energy, metal production, pipe industry, railway sector, and more.

These ultrasonic testing machines also find broad application in the aerospace and automotive sectors, where they are used to measure the precise thickness of materials and check their quality, particularly those designed to perform in demanding conditions. In the power generation and petrochemical industries, portable ultrasonic testing equipment is applied for weld inspection and corrosion monitoring.

Additionally, portable flaw detectors perform ultrasonic testing (UT) to detect cracks and assess the structural integrity of forged parts in industrial equipment and machinery. This is essential for all safety-critical applications.

In the railway sector portable UT flaw detectors can be used to detect and measure the depth of defects in rails, welds, and railcar and locomotive components.

Thanks to their compact design and mobility, portable flaw detectors greatly expand the capabilities of NDT, allowing inspections to be performed virtually anywhere, at any time. These lightweight, self-contained instruments are essential for NDT specialists who frequently travel between sites or work in environments where the size and weight of inspection equipment are crucial.

Types of Portable UT Flaw Detectors by OKOndt GROUP

• Sonocon B: This is the lightest manual compact flaw detector in the OKOndt GROUP's ultrasonic device lineup, weighing less than 2.2 pounds (1 kg). It accurately detects and localizes various types and sizes of defects, even under unstable acoustic contact conditions. The device has attachment lugs that allow NDT specialists to fasten it securely and conveniently to their chest mount on work clothing, keeping it within easy reach.
• Sonocon BL: This is a desktop flaw detector with a larger screen than the Sonocon B. It comes in either plastic or metal cases. It has an integrated, fold-out stand that allows users to conveniently adjust the screen angle when placing the device on a table or pipe. The device can also be hung if necessary.

Advantages of Portable UT Flaw Detectors by OKOndt GROUP

• User-friendly. The well-proportioned 800 × 480 pixel display and keyboard backlight deliver clear, easy-to-read data while minimizing eye strain during long inspections. All essential settings are within quick reach via intuitive keyboard shortcuts and a handy Quick Access Menu.
• Wide-ranging features. Portable ultrasonic flaw detectors offer more than a dozen operating modes. These include precise thickness measurement with a dedicated marker, automatic signal amplitude control, acoustic contact quality monitoring, and other advanced functions. They also provide automatic calibration for different transducer types and the simultaneous construction of three ultrasonic signal amplitude diagrams, allowing for the efficient rejection of defective parts. Various ultrasonic signal detection modes—including radio signal, positive half-wave, negative half-wave, and bipolar detection—help adapt the flaw detector to different defect types and inspection conditions, improving accuracy and reducing false positives. This ensures reliable and efficient inspections.
• Reliable in Challenging Conditions. Manual ultrasonic flaw detectors can operate in demanding environments. Their rugged, IP65-rated casing provides full protection against dust and water. They perform reliably across a wide temperature range from -22°F to 122°F (-30°C to +50°C), making them suitable for both hot and cold conditions. These devices are also resistant to ionizing radiation and operate consistently in humid environments, ensuring durability and dependable functionality in challenging industrial settings.
• Operation with all probe types. The set of UT transducers for portable flaw detectors is customized according to the customer's requirements and the specific inspection tasks for parts and objects. For example, ultrasonic testing of rails and welds may require delivery sets that include different straight beam contact transducers, angle beam contact transducers, and straight beam contact dual element transducers.
