The Hermine Scanner in Corrosion Inspection
The Hermine Scanner marked a turning point in the field of corrosion inspection on metallic surfaces. Described as a "major technological breakthrough" by Bureau Veritas, this portable device dedicated to ultrasonic thickness measurement enabled the optimization of large surface inspections while delivering unmatched precision.
A benchmark product
Although the Hermine Scanner is no longer available for sale, it remains a benchmark of advanced technology in the world of industrial inspection — and its design principles continue to influence today's NDT tools.
A revolutionary phased-array corrosion scanner
The Hermine Scanner introduced three major innovations that set it apart in the field of corrosion inspection:
Multi-sensor array
Between 3 and 9 probes for simultaneous, high-density measurements — significantly reducing inspection time while increasing data reliability.
Onboard electronics
Integrated console enabling real-time data acquisition and storage without external equipment — fully autonomous and easy to deploy.
Built-in positioning
Instant corrosion mapping with real-time visual feedback — helping maintenance teams anticipate and plan interventions efficiently.
Major advancements in corrosion detection
- Ultra-precise ultrasonic measurements — detailed results on the condition of inspected metallic surfaces
- Reduced inspection time — fast measurements over large areas, optimizing maintenance operations
- Corrosion mapping — instantly exported data integrated into visual reports for easier analysis and decision-making
A design built for efficiency
Lightweight and compact, the Hermine Scanner was engineered for field usability above all:
Weight
5 kg — lightweight and portable
Adhesion
Magnetic system — unaffected by gravity once positioned
Operation
Fully wireless — no cables on site
Display
10" or 13" backlit color screen
Seamless data management. The control software, installed on a rugged PC, allowed for automated reports compatible with Excel and precise positioning of C-scans on layouts and photographs.
Its impact on corrosion detection methods continues to influence today's technologies dedicated to monitoring metallic infrastructure.
A "major technological breakthrough" — the Hermine Scanner still sets the standard for ultrasonic thickness measurement.
