What Rohmann does

Rohmann GmbH is a privately held, family-owned German manufacturer founded in 1977 and headquartered in Frankenthal (Palatinate), with a wholly-owned US subsidiary (Rohmann LP) established in 2006 in Spartanburg, South Carolina. The company specializes exclusively in eddy current testing (Wirbelstromprüfung) equipment for non-destructive testing (NDT) of electrically conductive materials, serving industrial customers in aerospace/MRO, automotive, railway, and energy/steel. Its technology exploits electromagnetic induction to detect cracks, verify heat treatment, identify material mix-ups, detect grinding burns, measure wall thickness, and inspect coatings — without surface preparation or coupling agents and at speeds up to several meters per second.

Rohmann's product portfolio spans handheld and portable devices (ELOTEST M2, M3, M6, B300, IS3), inline automated testers (ELOTEST PL600 and PL650), robotic and specialized inspection systems (EloScan, EloScan Compact, EloWheel/ELOWHEEL, WPG D340 Draisine for rail), a sensor range (absolute, differential, passing, segment, array), and proprietary software (ScanAlyzer, EloLine). The company holds a 2014 patent on the Eddy+ Process, which opened a thick-plate testing segment for the steel industry. R&D is conducted in collaboration with research institutions and DGZfP, of which Rohmann is a 40-year member.

Revenue is generated through hardware sales of instruments, sensors, and accessories, software licensing, and professional services including ET1/ET2 and array training delivered with TÜV Saarland, Vector Training, and Zeppelin. Distribution runs through direct enterprise sales, an international representative network, and the US subsidiary, with quote-based, multi-year contracts targeted at industrial OEMs and MROs. ISO 9001 has been maintained since 1999 and ISO 14001 since 2022; the company was recognized as a Hidden Champion by VDHC in 2022. Approximately 80 employees serve a global installed base including Siemens Power Generation Services, Dillinger Hütte, Eisenwerk Brühl, Lufthansa Technik, Etihad Airways Engineering, and Zeppelin Systems.

Direct peers

• Institut Dr. Foerster GmbH & Co. KG: German specialist in eddy current and magnetic flux leakage testing, headquartered in Reutlingen. The closest direct competitor to Rohmann — both are Mittelstand pure-plays in eddy current NDT serving aerospace, automotive, and steel customers. Foerster's product lines (DEFECTOMAT, MAGNETOSCOP, STATOGRAPH) overlap heavily with Rohmann's ELOTEST family.
• Zetec Inc. US-based eddy current and ultrasonic NDT equipment manufacturer (now part of Eddyfi Technologies). Competes head-to-head with Rohmann in aerospace MRO and power generation ECT, with overlapping handheld and inline product portfolios.
• Eddyfi Technologies (now part of Vitrek): Canadian advanced NDT company specializing in eddy current array (ECA), phased-array UT, and other electromagnetic inspection modalities. Competes with Rohmann in advanced ECT applications and has grown rapidly through M&A (acquiring Zetec, M2M).
• Sonatest Ltd: UK-based manufacturer of ultrasonic flaw detectors, thickness gauges, and phased array instruments serving aerospace, oil & gas, and manufacturing NDT. Overlaps with Rohmann in handheld portable inspection use cases and shared aerospace/industrial customers.
• NDT Systems Inc. (NDT Systems & Services): US-based supplier of eddy current and ultrasonic inspection equipment with products used in aerospace, rail, and power generation. Comparable product lines (eddy current probes, portable instruments) and similar customer base make it a relevant niche peer.

Broad incumbents

• Evident (formerly Olympus Industrial Solutions): Global NDT equipment powerhouse offering ultrasonic, eddy current, X-ray fluorescence, and videoscope products across aerospace, energy, and manufacturing. Far larger than Rohmann with global direct sales; competes in many of the same accounts but across a much broader product portfolio.
• Waygate Technologies (formerly GE Inspection Technologies): Broad-line industrial NDT and inspection solutions provider (now owned by Baker Hughes). Offers ultrasonic, radiographic, and remote visual inspection products used by Rohmann's aerospace and energy customers, but competes primarily through scale and service-network breadth.
• Magnaflux (a division of ITW): Manufacturer of magnetic particle, dye penetrant, and ultrasonic testing equipment (part of Illinois Tool Works). Sells into overlapping aerospace MRO and industrial inspection accounts with broader non-eddy-current product lines.
• Comet Group (YXLON / Hocking): Swiss-listed technology group with NDT holdings including YXLON (X-ray/CT) and the former Hocking eddy current business. Provides broad X-ray and eddy current NDT equipment to similar aerospace and automotive customers.

Others

• Prüftechnik (Emerson Reliability Technologies): Condition monitoring and vibration diagnostics specialist (now part of Emerson). Adjacent rather than direct competitor — Rohmann also inspects rotating equipment (turbines, generators for Siemens), and Prüftechnik is a complementary supplier in predictive maintenance programs.
