CLEVELAND, Aug. 30 -- Keithley Instruments Inc., a manufacturer of electrical test instruments and systems, announced today it has been awarded an R&D 100 Award for its combination model 6221 precision AC/DC current source, which can source low currents for characterizing semiconductor and nanotechnology materials, and model 2182A nanovoltmeter, which lets users make low-level electrical measurements in production and research facilities. Called "the Oscars of invention" by the Chicago Tribune, the R&D 100 Awards are presented by R&D Magazine and recognize what the magazine chooses as the 100 most innovative and technologically significant products introduced during the past year. The editors of R&D Magazine and a panel of independent industry experts select the winners. This is the 19th time that Keithley has been selected to receive an R&D 100 Award for its products. R&D Magazine will profile the winners in its September 2005 issue; an awards banquet is planned at Chicago's Navy Pier in October to distribute awards to the winners.
