The Sonatest Masterscan D-70 gives inspectors a fully capable set of tools and software for inspection across all applications. High near-surface resolution, strong penetrating power from its 450 V square and spike pulser, and an excellent signal-to-noise ratio are the hallmarks of the Masterscan range.
This BNC kit comes with DAC as standard plus the AWS and API software options, giving code-based defect sizing for structural welds and pipe straight out of the box. Features can be added and upgraded in the field, reducing downtime and keeping the instrument ready for new work.
Key Features
![]() | DAC, AWS and API sizing includedDAC comes standard, with up to 3 custom DAC curves on screen and DAC-to-TCG conversion. This kit adds AWS D1.1 calculations and API 5UE flaw sizing, so service companies can work to different customer codes with one instrument. |
High-power pulser with Active EdgeThe 100 to 450 V negative spike and square-wave pulser, with pulse widths from 35 to 2500 ns and a PRF up to 5 kHz, drives a wide range of probes into thick or attenuative materials. Sonatest's Active Edge mode sharpens near-surface resolution. | ![]() |
![]() | Rugged, tested and reliableThe enclosure is made from automotive-grade, impact-resistant materials with excellent water resistance. The D-70 has passed MIL-810G explosive testing, and environmental testing confirmed it works at temperatures above 55°C. |
UT-Lity data managementFree UT-Lity software lets you view and manage calibrations, A-scans, B-scans and thickness logs on the instrument and PC. You can also build custom report templates, export to PDF and update firmware as new releases become available. | ![]() |
Built for the Field
Full VGA color display
The transflective color VGA screen stays visible in any lighting, with adjustable brightness and 9 color palettes, including a black-on-white LCD emulation mode.
All-day battery
Up to 10.5 hours from a full charge keeps the D-70 working through a full inspection shift.
Fast setup tools
AutoCal calculates velocity and probe zero from two reference echoes, and Automatic Gain Control sets the gated signal to your chosen height. A reference waveform and active peak memory make comparisons quick.
Encoded B-scan ready
A Lemo 4-pin encoder input supports encoded B-scan work, and USB gives quick access to the on-board memory from a PC.
Room to grow
Add Split DAC, DGS/AVG, TCG, BEA, Interface Trigger, Corrosion or Dryscan software later as your inspection work expands.
