DKK-TOA Corporation has been a specialised manufacturer of diversified analytical instruments for laboratories, drinking water and wastewater treatment, environmental conservation and process control in various industries since it was founded in 1945. Areas with high industrial activity experience a continuing deterioration of air and water quality that, if left unaddressed, could prove detrimental to the population. Putting the spotlight on ecological accountability, DKK-TOA engineers air and water monitoring instruments to help companies implement environmentally friendly business practices that can make the world a much safer place. Green stewardship is at the heart of DKK-TOA's business. Celebrating its 70th anniversary this year, the company strengthens the development of environmental measuring instruments based on its own sensor technologies. To continuously develop cutting-edge products, DKK-TOA works with United States-based Hach Company, a leader in the analytical instrument field. The two companies have been collaborating for almost a decade, embarking on joint research and development projects. One product of the collaboration with Hach China is a heavy metal analyser. The partnership also allows DKK-TOA to market Hach products under DKK-TOA in Japan, and Hach to market DKK-TOA products outside Japan. This strategy enables both companies to leverage each other's sales networks. Hach China also helps DKK-TOA reach the Chinese market and obtain product approvals from the Ministry of Environmental Protection. With the help of Hach China, DKK-TOA has sought approval for the FPM-377 Particulate Analyzer, a device that monitors fine and coarse particulate matter measuring 2.5 micrometres (PM2.5). Minute PM2.5 dust can cause cardiopulmonary diseases and respiratory infections. Aside from China, DKK-TOA plans to grow its business through distributors in Thailand, Indonesia, Singapore and India to fulfil its vision of becoming a global company. Judging by its 55 consecutive months of profits, many companies trust in DKK-TOA. "Our customers are our top priority," says president Teruo Sasaki. "It is very difficult to grow continuously if you do not try to please customers."
