Description
Keithley 182 Sensitive Digital Voltmeter IEEE-488 GPIB Benchtop SDV
The Keithley 182 is a benchtop sensitive digital voltmeter (SDV) designed for precision low-level DC voltage measurements. It features a full front panel with grouped function buttons covering Range, REL, Trigger, Buffer, and Selection controls, along with a vacuum fluorescent display (VFD) that self-identifies on boot. IEEE-488 (GPIB) connectivity allows the 182 to be integrated into automated test systems and computer-controlled measurement setups.

Applications
The Keithley 182 is a purpose-built sensitive digital voltmeter for laboratory and production environments that require precise low-level DC voltage measurement. Instruments in this class are used in semiconductor characterization, materials research, precision component testing, and calibration labs where microvolt-level resolution matters. The IEEE-488 (GPIB) interface makes the 182 well-suited for integration into automated test equipment (ATE) racks alongside other GPIB-controlled instruments such as source-measure units, current sources, and switching systems. Keithley introduced the 182 as part of their classic line of precision benchtop meters in the 1980s, a period when IEEE-488 was the dominant bus for laboratory automation. The rear-panel BNC outputs — analog output, external trigger, and meter complete — allow it to synchronize with other instruments in a multi-instrument measurement chain without requiring a computer controller for basic sweep-and-trigger setups.
This Keithley 182 Sensitive Digital Voltmeter has been inspected and pulled from a working environment where it was previously in use. Photos show the unit powering on and displaying 'Model 182 SDV' on the vacuum fluorescent display, confirming it boots normally. The chassis shows typical cosmetic wear consistent with lab use — light scuffing and marks on the top and sides. The front-panel buttons and the blue 5-pin DIN input connector appear intact. Note: the probe is not included — this is the instrument only. Please view our photo set and contact us if you have any questions.
