Runs field inspections, in-lab testing, and monitoring instruments that detect corrosion and structural fatigue in energy and industrial infrastructure, organized across a North America services unit, a smaller international arm, and a products business that makes the sensors; oil and gas customers supply roughly half of revenue.
Runs non-destructive testing and asset-integrity services — field inspections, in-lab materials testing, and monitoring instruments — that detect corrosion, cracking, and fatigue in energy and industrial infrastructure before failure. A proprietary software layer ties the results into one asset-condition record.
A North America unit of field crews and labs produces most of the revenue; a smaller international arm covers Europe, the Middle East, Asia outside China and South Korea, and South America; a separate unit builds the sensors sold worldwide.
Oil and gas customers account for roughly half of revenue, with the rest spread across aerospace, defense, power generation, manufacturing, and public infrastructure; no single customer dominates the book.
Traces to a 1978 acoustic-emission sensor lab near Princeton, New Jersey, and listed on the NYSE in 2009 after years of acquisitions; a recent leadership change steers it toward cost discipline.
