You are offerding on one good used Keithley 2100 6 1/2 digit multimeter. This multimeter is in very good overall condition with light signs of use - there are some marks on the rubber bumpers. The screen is very bright and legible. This unit has recently had the filter capacitors that commonly go bad on these replaced with high quality replacements. The calibration seal was broken when this repair was performed. I checked main functions with my out-of-calibration Fluke 5100B calibrator, everything looks reasonably accurate. I ship promptly from central Pennsylvania.
