The Triplett model 630-na is a classic, rugged analog multimeter (Volt-Ohm-Milliammeter or VOM) known for its durability and high precision for an analog device, with the core model still manufactured today. This unit is in overall good condition with a small chip on the bottom corner as detailed in the photos. It comes with instructions, the original carry case and a set of new probes. It has not been tested for functionality or accuracy. This is one component from a large estate purchase so has not had extensive assessment.
