Keithley Low-Level, Sensitive and Specialty Instruments

Keithley introduced its first electrometer, the Model 200, back in 1951. Today, we offer scientists and researchers a wide array of industry-standard sensitive tools for characterizing low-level phenomena at the edges of the measurement envelope. Whether the application demands a precision current source, a nanovoltmeter, a picoammeter, or an electrometer, there’s a Keithley solution designed to help you make high accuracy measurements quickly and confidently.
