Vintage Triplett D.C. Voltmeter – Industrial Panel Meter (0–300 Volts)

Offered here is an original vintage Triplett D.C. voltmeter, a high-quality American-made instrument produced by the Triplett Electrical Instrument Company of Bluffton, Ohio. Known for precision and durability, Triplett meters were widely used in industrial, laboratory, and military applications.

This example features a 0–300 volt direct current (DC) scale, with a clear, easy-to-read dial and classic mid-century styling. Marked “1000 Ohms Per Volt”, this meter reflects the sensitivity standards of its era and is consistent with professional-grade instrumentation.

The face also displays patent markings (Patent 2,346,521 and 2,364,724 pending), helping date the piece to the WWII/post-war period when these meters were commonly deployed in technical environments.
