VOLTA 2 is a high-power 2-channel portable ultrasonic instrument custom-designed for Electro Magnetic Acoustic Transducer (EMAT) applications. It features patented pulser technology capable of generating from 1-10 cycles at up to 1,000Vpp to satisfy the most energy-demanding EMAT applications in a compact and rugged package.
VOLTA 2 uses Innerspec Technologies Operating Platform (ITOP) with NDT-WEB application software. The instrument broadcasts a WiFi signal that permits remote control of the instrument from the removable phone/tablet (included) or from any connected wireless device using a standard web interface.
