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.
Fast, cost-effective low current measurement solutions
Source and sink DC and AC low currents precisely down to pA levels
Measure resistances down to microohms with controlled current sourcing
Make low noise, nanovolt level voltage measurements and accurately characterize low resistance materials
