CLEVELAND -- Keithley Instruments, Inc. (NYSE:KEI), a leader in solutions for emerging measurement needs, announces Nano Days, a unique, on-line nanotechnology educational event from April 24 through April 26, 2007. During this virtual conference, the theme of which is VISUALIZE, CHARACTERIZE, REALIZE: The Future of Nanotechnology, leading researchers from academia and business leaders from industry will present cutting edge measurement technology for nanoscale devices and materials. For more information about the conference presentations or to register, visit www.keithley.com/nanodays. There is no charge to attend the three-day event.

Six live audio/visual seminars will be held during Nano Days. Two back-to-back seminars will be held each day of the three-day conference. Each seminar is approximately 45 minutes long and includes interactive question and answer during each seminar. Seminar topics and presenters include:

-- Advanced particle beam methods for nano-characterization and
   analysis
    -- Dr. Jens Greiser, FEI Company

-- In-situ correlation of mechanical properties, deformation behavior
   and electrical characteristics of materials using conductive
   nano-identification
    -- Ryan C. Major, Ph.D., Sr. Staff Scientist, Hysitron, Inc.

-- How to avoid self-heating effects on nanoscale devices
    -- Jonathan Tucker, Keithley Instruments, Inc.

-- Give your microscope a hand: Characterization of nanostructures
    -- G. Frayne, S. Kleindiek, B. Volbert, Kleindiek Nanotechnik

-- Electronic properties of zinc-blende wurtzite biphasic GaN
   nanowires and nanoFETs
    -- Mr. Benjamin W. Jacobs and Dr. Virginia M Ayres, Michigan State
       University

-- Measurement needs in nano-architectonics
    -- Dr. Kang L. Wang, Director of MARCO Focus Center on Functional
       Engineered Nano Architectonics (FENA) and Director of the
