VOLTA II is a high-power 2-channel portable ultrasonic instrument custom-designed for Electro Magnetic Acoustic Transducer (EMAT) applications.

VOLTA II features a patented pulser technology to satisfy the most energy-demanding EMAT applications in a compact and rugged package. Standard software built on Innerspec Technologies Operating Platform (ITOP) includes an intuitive menu to set up any EMAT application using standard sensors from Innerspec’s catalog for normal beam, angled beam, and guided waves.

Advanced application software is available with easy-to-use wizards to facilitate setup and analysis for MRUT (Medium-Range UT / 0-3 m), LRUT (Long-Range UT / 1-100 m), Rail Heads, Thin Welds, and other exclusive solutions.

The NDT-Web™ graphical interface permits real-time control of the instrument using the detachable ruggedized tablet provided with the instrument, or any other wireless device (MS Windows®,iOS™, Android). The user software integrates seamlessly with Innerspec’s NDT-Link™ portal to provide a complete suite of productivity tools including Asset Management, Remote Support, Data Sharing, and Reporting.
