The company, founded in 1946 by Joseph F. Keithley in a Cleveland, Ohio, workshop, designs, develops, manufactures and markets complex electronic instruments and systems geared to the specialized needs of electronics manufacturers for high-performance production testing, process monitoring, product development and research. Now part of Tektronix.
In September, 2010, the company agreed to sell itself to the Danaher Corporation, a Washington, D.C.-based conglomerate, for $21.60 per share. It was soon merged with Tektronix, Inc, which had been acquired by Danaher in 2007, and now exists wholly as a brand of Tektronix.
