Pioneering Combustion Analysis Since 1909

For over 100 years, Bacharach combustion analyzers have been made in America with a wealth of combustion analysis experience.

Founded by Herman Bacharach in 1909, the company initially focused its development and production on combustion analysis, air flow, and gas sensing instruments. Bacharach’s rich history with inventions, education, R&D initiatives, patented technologies, and corporate acquisitions makes it what it is today, a leading manufacturer of refrigerant and gas leak detection, from monitoring instruments and data solutions, to combustion and emissions analyzers.
