Riken Keiki GmbH

Riken Keiki manufactures industrial gas detection systems for hazardous environment monitoring, encompassing both fixed installations and portable personal monitors. Our proprietary sensor technologies—including infrared, catalytic combustion, and electrochemical cell designs—deliver reliable detection across a broad range of industrial gases and environmental threats. What differentiates our offering is nearly nine decades of specialization in gas detection combined with in-house sensor manufacturing. This vertical integration ensures we control quality at every stage and can innovate across sensor technology, instrument design, and system integration without relying on third-party components. Our heritage from the RIKEN research institute reinforces our commitment to uncompromised reliability and durability—critical for applications where detection failure has serious consequences.

We serve industrial facilities, manufacturing plants, chemical processing operations, and safety-critical environments where early gas detection prevents casualties and asset loss. Our systems are engineered for demanding conditions: refineries, mines, confined spaces, and facilities handling toxic or flammable atmospheres.
