How it started

History

John Fluke founded Fluke Corporation in June 1948 as the John Fluke Engineering Company, Inc., producing electrical test and measurement equipment. In November 1952, John Fluke moved the company to Seattle Washington, reincorporated as John Fluke Manufacturing Co., Inc. In 1959, the company raised outside capital with an OTC listing. The company then re-listed on the American Stock Exchange (symbol FLK) in 1967. In 1980 the company re-listed on the NYSE (symbol FKM).

In 1987, Fluke established a joint venture with the Test and Measurement subsidiary of North American Philips. The joint venture developed the 'Scopemeter', an instrument combining features of an oscilloscope and a multimeter. Fluke purchased the Test and Measurement subsidiary of Philips in 1993 for $41.8 million. The Philips PM series of measurement instruments was rebranded as Fluke.

Fluke was acquired by the Danaher Corporation in 1998. Danaher spun off several subsidiaries, including Fluke, in 2016 to create Fortive, Inc. (NYSE symbol FTV).

Purchase of DNI Nevada

In 2002, Fluke purchased DNI Nevada (formerly Dynatech Nevada/Neurodyne-Dempsey), a Carson City, Nevada based manufacturer of medical test equipment, best known for being the original makers of the FitTester 3000 quantitative respirator fit test machine. Fluke subsequently placed DNI Nevada under the Fluke Biomedical brand, and moved manufacturing to its Everett headquarters in 2004.
