The Silverwing Scorpion 2 is an ultrasonic testing (UT) robotic crawler system that uses patent protected technology to provide thickness readings of large asset components. Predominately used in the storage tank inspection industry, the Scorpion 2 provides remote access to a tank surface, eliminating the need for scaffolding or rope access. Until recently, it utilized a 5Mhz dry coupled wheel probe to gather thickness readings and provide permanently recorded data sets for analysis and reporting.
