Keithley

Keithley Instruments, now a cornerstone brand within the Tektronix portfolio, has established itself as a formidable force in the realm of measurement and test instrumentation. Its genesis can be traced back to 1946, when Joseph F. Keithley, driven by a passion for innovation, founded the company in Cleveland, Ohio. The Phantom Repeater, a groundbreaking device designed to amplify low-level electrical signals, marked Keithley's initial foray into the industry. However, it was the introduction of the electrometer that catapulted the company's trajectory, forever inscribing Keithley's name in the annals of measurement history. A testament to Keithley's unwavering commitment to innovation, the electrometer played a pivotal role in the company's expansion and solidified its reputation for developing highly sensitive measurement solutions. Over the years, Keithley's product repertoire has grown exponentially, encompassing a comprehensive suite of instruments and systems designed for high-performance production testing, meticulous process monitoring, cutting-edge product development, and groundbreaking research endeavors. Keithley's state-of-the-art products have become indispensable tools for engineers, technicians, and scientists across diverse industries, including the semiconductor, telecommunications, and scientific research domains. In 2010, Keithley's legacy was further enriched when it became part of Danaher Corporation, subsequently merging with Tektronix under the umbrella of the Fortive family of companies. Today, Keithley continues to stand as a beacon of innovation in power testing and measurement solutions, reinforcing its position as an industry leader.
