About Reckmann
RECKMANN GMBH develops and manufactures temperature sensors for industrial measurement and control technology in Hagen with around 160 employees. The portfolio includes thermocouples, sheathed thermocouples and resistance thermometers in standard and special versions, including explosion-proof designs, HV thermocouples and sensors made of precious metals. In addition to manufacturing, the company offers a wide range of calibration services through a DAkkS-accredited calibration laboratory in accordance with DIN EN ISO/IEC 17025, so customers receive sensors and calibration certificates from a single source. A service team maintains, adjusts and calibrates temperature sensors and industrial furnace systems directly on site. The offering is complemented by a testing laboratory and training courses through the R58 Academy, including AMS and CQI-9 training. The sensors are used in industries such as industrial furnace construction and heat treatment, steel and iron, chemicals, energy, glass, pharmaceuticals as well as the automotive and aircraft industries.
