ROESSEL Messtechnik

What ROESSEL Messtechnik does

RÖSSEL-Messtechnik GmbH is a German, family-owned manufacturer of electrical contact thermometers founded in 1945 in Dresden and headquartered in Werne. The company develops and produces thermocouples and resistance thermometers (including Pt100/Pt1000 variants), plus complementary transducers, connecting cables, connectors, and accessories, with a catalog exceeding 50,000 products. Its technical differentiation spans the full temperature spectrum, from cryogenic sensors capable of operating at liquid hydrogen temperatures (-253°C) using proprietary NTC glass-insulated thermistors, to high-temperature sensors exceeding 2,000°C, alongside miniaturized sensors with diameters as small as 0.15mm and high-voltage sensors for EV battery systems. A wholly-owned DAkkS-accredited calibration laboratory (CENTROCAL GmbH) provides accredited calibration services, and the company has expanded into seminars, training, and custom product refinement.

The company operates through five wholly-owned subsidiaries in Germany (Werne, Dresden), the Netherlands (Tempco B.V.), India (Tempco India, est. 2010), and China (Roessel Qingdao), enabling direct field sales and on-site technical consultation across Europe and Asia. Its go-to-market is enterprise-focused, with quote-based pricing determined by application specifications, and serves verticals including automotive R&D, hydrogen mobility, semiconductor fabrication, steel, furnace construction, and power plant technology. The business mixes hardware sales with recurring calibration services and training, and is differentiated by an unusually broad certification stack (ISO 9001, ISO 17025, AMS 2750, CQI9, ATEX, IEC-EX, DNV, GL, Lloyd's Register) that creates high regulatory entry barriers.
