Description
Keithley 2000 6.5-Digit Multimeter DMM GPIB IEEE-488 RS-232 Benchtop
The Keithley 2000 is a 6.5-digit precision benchtop digital multimeter (DMM) designed for high-accuracy laboratory, production, and research measurement applications. It combines wide measurement ranges across DC and AC voltage, current, resistance, frequency, and temperature with a 0.002% 90-day basic DC voltage accuracy specification — placing it in the same tier as professional-grade reference instruments. The instrument features a bright vacuum fluorescent display (VFD) and a full complement of front-panel function and range controls.

Applications
The Keithley 2000 is a workhorse precision DMM widely used in electronics laboratories, semiconductor test, quality assurance, calibration labs, and automated test equipment (ATE) setups. Its GPIB (IEEE-488) and RS-232 interfaces make it straightforward to integrate into computer-controlled test systems — a core reason it became one of the most popular benchtop DMMs of the 1990s and 2000s. Keithley (now part of Tektronix/Fortive) built the 2000 to serve applications requiring higher accuracy than a standard 4.5-digit handheld meter but without the cost of a full-featured 8.5-digit reference standard. It is commonly found in university electronics labs, R&D environments, component characterization, and production line verification, and continues to be a sought-after instrument on the used market because of its well-regarded accuracy specs and robust GPIB support for legacy ATE systems.
This Keithley 2000 6.5-Digit Benchtop Multimeter has been inspected and appears to be in good used condition. The unit powers on — the VFD display is lit and reading values in multiple photos. The front panel buttons, binding posts, and input terminals all appear intact and undamaged. The rear RS-232 and IEEE-488 GPIB ports are present and appear clean. The chassis shows minor surface wear and light scuffing consistent with normal lab use, but no significant damage. Test leads are included as shown in the photos.
