Sitescan D-50


Sonatest Sitescan Flaw Detectors have always meant highly reliable, technician focused flaw detection equipment and this model builds on that tradition.

The Sitescan D-50 offers the end user an entry level broadband flaw detector in the popular and portable casing of the established D-Series; with a full VGA display, a 50nS (Spike) 200V, a Pulser 0.5dB gain resolution and an optional rubber boot.

Typical applications are Weld Fabrication, Corrosion Detection, Forgings & Castings 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 Sitescan D-50's outstanding battery performance, which is up to 18 hours from full charge. The Sitescan D-50's enclosure is constructed using automotive grade impact resistant materials and offers 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 55°C. The Sitescan D-50 has a colour transflective VGA display, providing high visibility in any lighting conditions. Maxi,u, readability is achieved through adjustable brightness and the choice of 9 colour palettes, including a black-on-white LCD emulation mode.

Advanced Defect Sizing Tools as Standard

Weld an pipe inspection are major applications for the Sitescan D-50 which is 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.
