Horiba is a Japanese manufacturer of precision instruments for measurement and analysis. They claim to have 80% of the world market for instruments that measure and analyze automobile exhaust gas, and also make instruments for environmental, medical and scientific applications. Horiba was founded in 1945 by Dr. Masao Horiba, who graduated in nuclear physics from Kyoto University. In the early 1950s he started mass-production of pH meters; the present company was registered in 1953. From 1959 until 2002, Hitachi was a principal shareholder, and the two companies retain close connections. In 1972 the company established subsidiaries in America and Europe. In 1996-7 Horiba acquired two French companies: the specialist blood cell counter maker ABX SA in 1996, and optical equipment maker Instruments SA in 1997. In 2005 Horiba acquired German company Schenck Development Test Systems, expanding the automotive market product range to include engine and driveline testing tools, including brake testing and wind-tunnel balances, and the Interautomation Group of Ontario, Canada, with its Real-Time pre-emptive kernel Linux-based ADACS data acquisition and control software suite.
