Jonathan Kroener, Head of Business Development at Rohmann GmbH. Eddy current testing equipment (ECT) is one of the most extensively used, non-destructive techniques (NDT) applied to evaluate electrically conductive materials for characteristic differences, welding defects, and discontinuities. However, depending on the application, ECT techniques are strongly affected by the details of probe structure. Meeting these technical requirements demands in-depth knowledge and experience in the field of ECT techniques.
For over 45 years, Rohmann GmbH has been a leader in developing and manufacturing ECT testing devices and systems for crack detection, testing of heat treatment conditions, material sorting inspection, and grinding burn testing. The family-owned business, headquartered in Frankenthal, Germany, provides ECT solutions for eminent aviation, automotive, rail, and steel companies. Its state-of-the-art product line includes small hand instruments, line devices, large robot-controlled test systems, digital test equipment, and more.
Experts at Rohmann focus on acquiring a comprehensive grasp of a customer’s individual technical and application requirements before systematically adapting the winding and shape of probes, in close collaboration with leading labs, technology partners, and applied research departments. “Our products are not mass-produced. All of our probes, cables and devices are assembled by hand to guarantee the quality, their robustness, and above all, a high accuracy of detection,” explains Jonathan Kroener, Head of Business Development at Rohmann GmbH.
In addition, the company leverages cutting-edge technology and interdisciplinary collaborations to develop customized ECT devices, specially designed materials, and systematically advanced solutions for existing and new NDT activities.
Since its inception in 1977, by Jürgen Rohmann, capacity for innovation and quality has been the hallmark of Rohmann. It was the first to develop the portable eddy current inspection device (Rototest B588, Elotest B1), which is still in operation today and regularly referred to by customers for signal quality. Furthermore, it was also the forerunner in the market to introduce bore inspection solutions using a rotating probe and inspection kits for checking aircraft engine components (manual and automatic). Over the years, Rohmann’s products and solutions have been copied repeatedly. To maintain the highest international standards, the company focuses on continuously improving its employees’ qualifications, further developing all quality processes, and permanently optimizing all its technical facilities.

With the right combination of instruments and probes, ECT enabled the detection of a wide range of defects in materials and finished components, ultimately increasing product quality, safety and efficacy. Today, the second generation, Petra Rohmann, and her mother, Ines Rohmann, are at the company’s helm, working to consistently promote and maintain its ideals of quality, customer satisfaction, and dedication to making life safer. Whether testing is automated and integrated into the manufacturing line or conducted at a bench-top with a handheld instrument and probe, Rohmann continues to evolve ECT technologies to produce inspections that are swift to set up and complete. By leveraging its extensive experience, the company understands the day-to-day challenges modern companies face in production to competently supply unique and individual solutions for every testing task and requirement. Rohmann strikes the right balance of inspection speed, detection capability, expertise, and cost-effectiveness with its technical solutions, customer experience, and the premiumization of products and systems for ECT.
