The company’s mission centers on enabling professionals to measure, test, troubleshoot, and maintain equipment to ensure business continuity and infrastructure reliability. Essentially, Fluke manufactures tools that allow professionals to identify faults and verify operational integrity.

Foundation (1948)

Fluke was established in 1948 by John Fluke Sr., an MIT-educated engineer and U.S. Navy veteran of World War II. The company originated in a basement workshop in Springfield, Connecticut, where it developed its first major product: a precision volt-amp-watt meter (VAW meter). This instrument measured key electrical quantities including voltage, current, and power.[4]

Early adoption by major corporations such as General Electric provided the nascent company with a significant foothold in the industrial electrical measurement sector.[5]

Incorporation and Expansion (1953–Present)

In 1953, the business was incorporated in Washington State as the John Fluke Manufacturing Company, Inc. The choice of location was personal, as founder John Fluke was born in Tacoma, Washington.[6] Over the following decades, the company expanded its portfolio from power meters to encompass a comprehensive range of electrical and electronic measurement instruments.

A pivotal moment in the company’s history was the expansion into digital multimeters (DMMs). These devices integrate multiple electrical measurement functions—such as AC/DC voltage, AC/DC current, resistance, continuity, capacitance, frequency, temperature, and diode testing—into a single unit.

Fluke introduced its first handheld digital multimeter in 1977, marking a significant milestone in portable test equipment.[7] The handheld DMM subsequently became the product category most synonymous with the Fluke brand. Today, the company offers numerous DMM families ranging from essential electrician models to advanced industrial and engineering meters.[8]

Fluke gradually evolved beyond standard electrical meters into a broader industrial measurement and reliability technology company.[9] Its expanded portfolio eventually included:

• Electrical testers and clamp meters
• Power-quality analyzers and portable oscilloscopes
• Insulation testers and thermal imagers
• Temperature instruments and calibration equipment
• Network cable certification tools
• Vibration monitoring and laser alignment systems
• Industrial and asset-management software

Acquisitions and Specialized Growth

Strategic acquisitions have been central to Fluke’s growth into specialized measurement markets. In 2000, the company acquired the Precision Measurement Division of Wavetek Wandell Goltermann. Subsequent acquisitions of Hart Scientific and DH Instruments enhanced its capabilities in temperature, pressure, and flow calibration.[10]

Further expansion into biomedical testing, network infrastructure, process instrumentation, condition monitoring, and industrial software created the diverse family of businesses and brands associated with Fluke today.[11]

Fluke is not an independent publicly traded entity; it is a wholly owned subsidiary of Fortive Corporation, a publicly traded industrial technology group.[12] Fortive identifies Fluke as a core operating company and a provider of industry-leading test and measurement tools.[13]
