What Teseo does

Teseo S.p.A. is an Italian EMC (Electromagnetic Compatibility) and RF (Radio Frequency) test and measurement specialist, founded in 1978 and headquartered in Druento (Turin). The company designs and manufactures fiber optic signal transmission systems, RF power amplifiers (broadband solid-state and TWT up to 50,000 watts), antennas spanning 10 kHz to 50 GHz, RF sensors and field probes, modular production test benches (TCU, SATB, AM-TB), and turnkey EMC laboratories. It also produces ground support equipment for aircraft maintenance and the T-SCAN 540 contactless medical temperature scanner. Manufacturing, calibration, and EMC testing operations are co-located at the Druento facility.

The company monetizes through a mix of hardware sales (standard catalog items and fully customized solutions), professional services (accredited EMC testing, RF measurements, and calibration), and managed services (preventive and corrective maintenance, asset management). Pricing is uniformly quote-based given the custom, certified nature of solutions. Teseo holds ACCREDIA 00137 accreditation for calibration of HF power, electromagnetic field strength, and frequency measurements, alongside ISO/IEC 17025, ISO 9001, and ISO 10012 certifications. It is a National Instruments Platinum Alliance Partner, giving it a privileged position in the calibration and integration of NI hardware.

Teseo serves enterprise customers across four vertical segments: aerospace, space, and defense (Alenia Aermacchi, UTC Aerospace Systems Italy, SELEX ES, OTO Melara, WASS, Eurofighter Jagdflugzeug GmbH); automotive and transportation (Ferrari, FCA, Magneti Marelli, Honeywell Turbo Technologies, SKF); medical, electronics, and energy (Esaote for MRI calibration); and general RF applications/EMC testing. The company operates as a specialized subsidiary within Eiffage Énergie Systèmes under the Clemessy brand, leveraging the parent group's industrial relationships and capital base while retaining the Teseo product brand.
