What ETS-Lindgren does

ETS-Lindgren is a global designer and manufacturer of electromagnetic compatibility (EMC) test and measurement systems, RF shielding solutions, wireless over-the-air (OTA) testing infrastructure, and MRI shielding systems. Formed in 1995 in Austin, Texas, through the merger of EMCO, Rantec, and Ray Proof, and later expanded via the 2000 acquisition of Lindgren RF Enclosures (which doubled company size) and the 1997 acquisition of Euroshield OY in Finland, the company now operates as a wholly-owned subsidiary of ESCO Technologies (NYSE: ESE). Its product portfolio spans RF-shielded chambers (FACT 3, AMS-5700 series CATR systems, GTEM cells), absorber materials (Convex, DuraSorb, FerroSorb), antennas, RF power amplifiers, positioners, and software suites (EMQuest, TILE!, VisionTRX, VALET, ProbeView). Proprietary technologies include RedEdge HEMP/EMP/IEMI pulse protection, MACS/D active magnetic compensation for MRI, and the DRAMS dual-robotic antenna measurement system developed with Boeing.

The company manufactures over 90% of chamber components in-house and delivers turnkey project execution managing all mechanical, electrical, and RF interfaces, positioning it as a single-source provider for complex test environments. ETS-Lindgren serves six primary verticals — Aerospace & Defense, Wireless/Telecom, Healthcare/Medical, Automotive, Utilities/Energy, and Government/Security — plus secondary exposure to IT/Data Centers and Academia/Research. Revenue is generated through custom-engineered hardware sales, one-time software licenses, and recurring professional services (calibration, maintenance, repair, consulting, training). Pricing is quote-based and not publicly disclosed; the company operates an enterprise field sales model supported by a global sales and service network spanning North America, Europe, and Asia (Singapore, Japan, China, Taiwan, India). The company holds A2LA accreditation (Lab Cert #1207.01) for ISO/IEC 17025 calibration services and is recognized for TEMPEST/SCIF-compliant solutions.

The company's customer base includes Boeing (co-developed DRAMS antenna testing system), Mount Sinai (MRI enhancement via MACS/D), and IMQ S.P.A. (10-meter EMC test chamber in Italy), with 50,000+ installations worldwide and 10,000+ shielding systems deployed globally. The company maintains active participation in industry events including GlobalEM 2026 (Seoul) and TechnoFrontier 2026 (Japan), and markets through technical resources, webinars, a podcast, case studies, BIM models, and earned media channels.
