Since our company was founded in 1939 under the umbrella conglomerate of RIKEN, our management philosophy has been to create safe working environments. Our science and technology research laboratories have developed industrial gas detection warning devices, specialising in monitoring harmful gases in the work environment, as well as for explosion prevention from combustible gases. Without compromise, we continue to challenge ourselves to be technological leaders, developing and manufacturing a wide range of industrial gas detection systems and monitors. From large-scale gas detecting alarm systems to small-sized personal gas monitors for safety protection; used in many industries including semiconductor and LCD plants, petroleum complexes, steelworks, various tankers, oil storage stations, underground gas facilities, and volcanoes. Experts in gas detection for over 80 years The “RIKEN Gas Detector” utilising the principle of light wave interference, was exhibited at the 1937 Paris World Exposition. Its subsequent use greatly contributed to the prevention of accidents in coal mines where many fatalities were prevalent at the time. On the 15th March 2019 we celebrated our 80th anniversary. Supported by our history and tradition we shall further improve long established technology, and continue to innovative. Developing reliable quality products in response to the diverse needs of industry.
