Keithley
Keithley, now part of Tektronix, is the specialist name in low-level and precision electrical measurement, and this catalogue carries source measure units, bench multimeters, dataloggers and data acquisition systems.
Keithley source measure units are the standard tool for semiconductor and materials characterisation, because sourcing a voltage while measuring picoamp currents in the same feedback loop avoids the timing and grounding problems of separate instruments. For the multimeters, the specification that matters is basic DC accuracy over a stated period and temperature range rather than the digit count on the display.
