Kahn Industries operates as part of The Kahn Companies group, a family-owned multi-million dollar
manufacturer of test equipment, air and gas purification systems and electronic instruments. Founded in 1945,
the company is a world leader in dynamometer technology and is the only American manufacturer of a complete
line of hydraulic engine dynamometers.
Specializing exclusively in hydraulic dynamometers and associated equipment, Kahn Industries pioneered
the design concept of the portable, flange trunnion-mounted hydraulic dynamometer over forty years ago. Since
then, significant advances have been continuously incorporated, particularly in the areas of higher operating
speeds and increasingly sophisticated computer-interfaced, closed-loop controls. The result has been a widely
acknowledged leadership in product performance and reliability. With designs capable of absorbing up to 100,000 hp
(75,000 kW) and operating at speeds up to 100,000 rpm, Kahn Industries dynamometers are now at work in engine
test facilities around the world. Visit us at www.kahn.com.
