DKK-TOA Corporation was formed in 2000 through the merger of Toa Denpa Kogyo (founded 1944 in Koishikawa, Tokyo) and Denki Kagaku Keiki (founded 1945 in Musashino, Tokyo). The company traces its roots to these two predecessors: Toa Denpa Kogyo was established in 1944, and Denki Kagaku Keiki in 1945. In 1954, the predecessor launched the benchtop pH meter HM-5(A), which sold over 20,000 units and received 'Analytical Instrument/Scientific Instrument Heritage' certification in 2014. In 1961, the company listed on the Second Section of the Tokyo Stock Exchange. In 1963, it built the Sayama Factory (now Sayama Technology Center) in Sayama, Saitama. Denki Kagaku Keiki developed Japan's first automatic nitrogen oxide analyzer under a Ministry of Health and Welfare project, entering the atmospheric analysis instrument field. In 1968, the head office building in Takadanobaba, Shinjuku was completed. In 1970, under commission from the former Ministry of Construction, Japan's first river water quality monitoring devices were installed on the Yodo and Tama rivers. In 1973, Iwate Toa Denpa (now Iwate DKK) was established in Tono, Iwate as a production subsidiary. In 1979, the company obtained a medical device manufacturing license from the Ministry of Health and Welfare and began selling clinical measurement equipment, entering the biochemistry and medical device fields. In 1989, Denki Kagaku Keiki built the Tokyo Factory (now Tokyo Engineering Center) in Higashiyamato, Tokyo. In 1990, Yamagata DKK (now Yamagata DKK) was established in Shinjo, Yamagata as a production subsidiary. In 1995, it obtained ISO9001 certification. In 2000, DKK-TOA Corporation was born and obtained ISO14001 certification. In 2002, it launched the total nitrogen/total phosphorus/COD automatic measuring device NPW-150 (now NPW-400). In 2003, it provided A4-size automatic water quality measuring devices MWA4-70 (now MWB4-72) to 78 locations in the Tokyo Tama area. In 2005, it made Bionics Instrument a wholly owned subsidiary through share exchange, expanded the industrial gas detection alarm division, and signed a business and capital alliance with HACH.
