Sonatest Masterscan D-70

Sonatest Masterscan D-70 Masterscan name has always assured the technician of robust instrument construction combined with exceptional performance.

Sonatest Masterscan D-70 Features can be added and upgrades performed in the working environment, reducing downtime and increasing working flexibility. High levels of near surface resolution, penetrating power (450V pulser – square and spike) and excellent signal to noise ration are key functions in the Masterscan range.

Sonatest Masterscan D-70 This instrument offers the inspector a fully capable and functional set of tools and software for inspection across all applications. Capabilities include encoded B-Scan, Advanced Thickness logging and Dryscan capability in a portable enclosure.

Typical applications are Weld Fabrication, Corrosion Detection, Composite Inspection, Bond Testing, Forgings and Castings, Power Generation (including EMATS and general UT inspection).


Reliable, Rugged & Robust

An instrument’s ability to perform in harsh environments with proven reliability is an important aspect of flaw detector ownership and this is enhanced by the Masterscan’s outstanding battery performance which is up to 18 hours from full charge. The Masterscan’s enclosure is constructed using automotive grade impact resistant materials, offering excellent water resistance. Explosive Testing MIL810-G standards have been passed, together with environmental testing which has confirmed the instrument fully functioning at temperatures above 55ºC. The Masterscan D-70 has a colour transflective VGA display and maximum readability is achieved through adjustable brightness and the choice of 9 colour palettes, including black-on-white LCD emulation mode.

Advanced Defect Sizing Tools as Standard

Weld and pipe inspection are major applications for the Masterscan D-70 and they are equipped with the latest software tools for defect sizing. The use of integrated sizing software reduces analysis time and speeds inspection. Multiple standard sizing techniques are essential for service companies working to different customer standards, especially as service work becomes more international and operators are required to work to different codes.


UT-Lity Data Management Software

UT-Lity software provides everything you need to manage your inspection data. The standard version is FREE with every instrument and gives you the ability to view, move and manage Calibrations, A-Scans, B-Scans and Thickness Logs both on the instrument and on your PC. With UT-Lity you can also create customised inspection report templates, cut-n-paste information to other applications and create printable pdf documents.

  • Load, store, manage files both on the PC and on a connected flaw detector
  • Save, analyse, colour code and export thickness logging data to spreadsheets/asset management software
  • Update the Flaw Detector and Firmware as and when updates become available on our website
