Correge

What Correge does

CORREGE is a French industrial specialist in temperature measurement, founded in 1967 and headquartered in Chaignes, Normandy, with a secondary operations site in Bourg-Argental. The company designs, manufactures, and services industrial thermocouples and Resistance Temperature Detectors (RTDs / thermosondes) under the Correge and Berger brands, offering more than 40,000 product references spanning cryogenic (-196°C) to ultra-high-temperature (1550°C) applications. Core technologies rely on the Seebeck effect and platinum resistance principles, with proprietary sheathing materials (Inconel, HASTELLOY), ceramic high-temperature assemblies, multipoint probes, skin thermocouples, and instrumented wafers for semiconductor manufacturing. The business also runs a COFRAC-accredited calibration laboratory under NF EN ISO/IEC 17025, covering -95°C to 1350°C, alongside an on-site CORREGE Services field team that performs furnace mapping, sensor repair, helium leak testing, laser welding, brazing, and quality control across France.

Revenue is generated through two streams: hardware sales of sensors and accessories, and professional services (on-site calibration, furnace temperature mapping, metrology, repair, and maintenance). Customers are B2B industrial buyers in demanding verticals including aerospace and defense (AMS 2750 thermal treatment, RTCA DO-160 qualified embedded sensors), nuclear, oil and gas/hydrogen (ATEX/IECEx explosive atmospheres, cryogenic hydrogen storage), semiconductors (instrumented wafers), energy metering (MID-certified paired probes), industrial manufacturing (foundry, cement, plastics, aluminum), mobility (automotive test benches, rail), pharmaceuticals/laboratories, and agri-food. The go-to-market is sales-led direct engagement via technical sales representatives and corporate website inquiries, supported by the CORREGE Services field team delivering recurring on-site work.

The company maintains a substantial regulatory moat through ISO 9001, EN 9100 (aerospace), ATEX, IECEx, CCC-Ex, MID (Directive 2014/32/EU), PESO (India), and KCs (Korea) certifications, and is a member of NAE (Normandie Aéronautique Espace) and the BPI France acceleration program for nuclear sector development. Ownership is private (SAS CORREGE, share capital €180,000), led by legal representative Guillaume Fèvre and Commercial & Marketing Director Frédéric Freon, with no disclosed external parent or institutional backing.
