Medtherm Corporation

What Medtherm Corporation does

Medtherm Corporation designs and manufactures precision heat flux sensors and thermocouples for mission-critical aerospace, defense, space, and industrial thermal measurement applications. The company's core technology stack rests on three proprietary sensor architectures: Schmidt-Boelter Thermopiles, Gardon Sensors, and coaxial surface thermocouples, with the latter offering approximately one-microsecond response time for transient measurements such as hypersonic wind tunnel and flight testing. Its catalog spans the GTW, 8, 24, and 64 Series heat flux transducers (the 64 Series is engineered for ASTM and ISO fire and flammability testing), TCFW fine-wire and TCS coaxial thermocouple probes, high-temperature probes, furnace heat flux probes, and coaxial-thermocouple calorimeters, marketed as over 10,000 available configurations. Medtherm's products are flight-qualified on a long list of US space and missile programs including Shuttle, Delta, Atlas, Orion, SLS, THAAD, MX, SICBM, SeaLaunch, X-33, Aries 1X, Pegasus, Titan, and LLV.

The firm generates revenue through direct B2B sales of specialized sensors and NIST-traceable calibration/recalibration services compliant with ISO/IEC 17025 and ANSI Z540-1; pricing is quote-based and not publicly disclosed. Customer concentration is implicit in the addressable market, with aerospace primes, defense systems integrators, hypersonic test programs, and space mission programs as primary buyers. The company is headquartered at 4900 Bradford Drive, Suite 101, Huntsville, Alabama, and has operated since November 2023 as a wholly-owned subsidiary of Raptor Scientific, a diversified test-and-measurement platform that also owns Eastern OptX, In-Phase Technologies, King Nutronics, Space Electronics, Sensor Concepts, and TestVonics. Medtherm has no subsidiaries of its own, and its marketing and lead-generation presence now runs through the parent company's corporate site.
