OKOndt Sonocon BL Ultrasonic Flaw Detector, UT Basic Version
SKU: SONOCON-BLUT
A rugged portable ultrasonic flaw detector with a big 7.2" display, dual-mode 400 V pulser, 0.2 to 27 MHz receiver and code-ready DAC, DGS and AWS evaluation, built for field and industrial inspection.

| 7.2"800 × 480 display | 400 VSquare-wave pulser | 6 kHzMax PRF | IP65-30°C to 50°C |
The OKOndt Sonocon BL is a latest-generation portable ultrasonic flaw detector. It uses high-end electronics and a rich set of modes and software features to handle virtually any task a portable UT instrument can. In the "UT" version, it covers every function a powerful flaw detector needs, from setup to defect search and advanced evaluation.
Its 7.2" high-resolution display lets inspectors follow the A-scan without strain, even from a distance. A shock-resistant case with rubber pads and a 4-position folding handle make it equally at home in the field, in the plant or on the bench.

Key Features
![]() | Solid build, really big screenAn ergonomic, shock-resistant ABS case with extra rubber pads is designed for both field and industrial conditions. The 7.2" 800 × 480 display, combined with a well-designed interface, makes the A-scan easy to read without eyestrain. |
Place it anywhereThanks to its case design and 4-position folding handle, the Sonocon BL sits comfortably on a table, a pipe or the test object, or can be hung up. It can also be fixed to the inspector's chest for better mobility. | ![]() |
![]() | Code-ready flaw evaluationThe built-in DAC system builds curves to ASME, ASME III, EN 1712, EN 1713, EN 1714, JIS Z3060, GB 11345 and GB 4730, with up to 128 points and 6 extra curves, plus 20-80 and DAC-to-TCG conversion. DGS builds up to 3 curves, and AWS D-rating is calculated per D1.1 and D1.3. |
"Don't browse menus, just push a button"The most-used functions sit directly on the keyboard, one or two presses away, which makes setup and evaluation several times faster. Context backlighting, menu hints and three menu presets (Full, Simple 1 and Simple 2) help new users get up to speed quickly. | ![]() |
Built for the Field
Dual-mode pulser
Choose spike (50 or 300 V) or square-wave mode from 50 to 400 V with 20 to 1,000 ns pulse energy. Together with damping, this gives wide control over echo shape, length and amplitude.
Wide-band receiver
The 0.2 to 27 MHz bandwidth comes with 22 broadband and narrow-band filters, 0 to 110 dB gain in 0.1 dB steps and signal averaging up to 64× for a cleaner signal at high gain.
Smart indication search
Legs Marking colors the A-scan by leg to show reflector depth at a glance, Smart Zoom shows a zoomed gate alongside the full A-scan, and Estimate mode catches and freezes the strongest echo during a blind scan.
Fast automatic calibration
Built-in auto calibration routines work with straight beam, angle beam and Rayleigh wave probes, on standard blocks or directly on test pieces.
Harsh-environment ready
The IP65 case works from -30°C to 50°C (-22°F to 122°F), resists ionizing radiation and is designed for high-humidity conditions.
Storage and connectivity
Store setups and datasets with A-scans in 2 GB of memory, expandable to 64 GB. USB and LAN ports connect to PCs and external devices, and the included PC software handles results analysis and reporting.
Room to grow
The same instrument can run the "Thickness gauge +" software version, turning it into an advanced A-scan thickness gauge with corrosion mapping.
