OKOndt Sonocon B Ultrasonic Flaw Detector, UT Basic Version
SKU: SONOCON-BUT
A lightweight 0.95 kg ultrasonic flaw detector with a dual-mode 400 V pulser, 0.2 to 27 MHz receiver and code-ready DAC, DGS and AWS evaluation, supplied as a complete kit with straight and angle beam probes.

| 0.95 kg2 lb with battery | 800 × 4804.5" display | 400 VSquare-wave pulser | IP65-30°C to 50°C |
The OKOndt Sonocon B is a next-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.
Weighing just 0.95 kg (2 lb), it can be used comfortably with one hand, by left- or right-handed operators. The IP65 case, -30°C to 50°C operating range and sunlight-readable display make it at home in the field. This kit comes ready to work with straight beam and angle beam probes, a connection cable and PC software.
Key Features
![]() | Comfortable and lightweightThe ergonomic shape and hand strap let you operate the Sonocon B with a single hand, which matters most in the field and when working at height. A high-contrast 800 × 480 display of optimal size helps prevent eyestrain on long shifts. |
Built for harsh environmentsThe display stays readable in direct sunlight, and the case is rated IP65 for dust and water. The Sonocon B operates from -30°C to 50°C (-22°F to 122°F), resists ionizing radiation and is designed for high-humidity conditions. | ![]() |
![]() | 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. |
Smart indication searchLegs Marking colors the A-scan by down- and up-going legs to show reflector depth at a glance, and Smart Zoom shows a zoomed gate alongside the full A-scan. Estimate mode finds the strongest echo during a blind scan, sets it to evaluation level and freezes it for you. | ![]() |
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×, which raises the signal-to-noise ratio even at very high gain.
"Don't browse menus, just push a button"
41 keyboard shortcuts, context-sensitive key backlighting, menu hints, a Quick Access Menu and three menu presets (Full, Simple 1 and Simple 2) make setup and evaluation several times faster.
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.
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.
