What UNION Instruments does
UNION Instruments GmbH is a Karlsruhe, Germany-based manufacturer of industrial gas analysis and measurement technology founded in 1919. The company designs, manufactures, and distributes analytical instruments for continuous, real-time determination of calorific value, heating value, Wobbe index, gas composition (CH₄, CO₂, H₂S, O₂, H₂, CO), and related process parameters in demanding industrial environments.
The product portfolio is organized into three core technology platforms: (1) the CWD combustion calorimeter series (BASIC, PLUS, HT, EXP, DPC, SPC) using thermal measurement principles for direct gas quality determination, with variants certified for hazardous locations (ATEX/IECEx in Europe, NRTL/SGS Class I Division 2 in North America); (2) the SIRA UV and IR spectroscopy series for selective process gas analysis, including residual oxygen, odorant (THT), VOC, and low-ppm methane detection; and (3) the INCA modular multi-component gas analyzer family (INCA1000 through INCA6000) with the CAM (Compact Analyzer Module) for biogas, biomethane, and natural gas applications. All products are designed for continuous 24/7 industrial operation in explosive atmospheres and extreme process conditions, and the company holds ISO 9001 quality management certification.
The business operates a B2B hardware sales model with quote-based pricing, generating revenue from equipment sales plus installation, calibration, and maintenance services. The wholly-owned subsidiary UNION Sensors GmbH (Lübeck) extends the technology base into environmental, oceanographic, and pressure/temperature sensing. Commercial distribution is dominated by a global channel partner network of more than 30 named regional distributors covering 60+ countries across Europe, the Middle East, Asia, the Americas, Africa, and Australia, supplemented by direct sales from Karlsruhe for key German accounts and complex applications. Target end markets include iron and steel production, biogas and biomethane upgrading, petrochemicals and refineries, natural gas infrastructure, glass and ceramics, and energy generation from waste.
