Vintage Westinghouse AC Voltmeter – Industrial Panel Meter (0–150 Volts)

Offered here is an original vintage Westinghouse alternating current voltmeter, a classic piece of American industrial instrumentation. This meter features a clean, easy-to-read dial marked from 0 to 150 volts AC, housed in a heavy-duty black metal case designed for panel mounting.

Manufactured in the USA, this unit is marked “Cal. for 400 cycles” and was intended for use in specialized electrical systems, likely aviation, military, or industrial applications where higher frequency AC was utilized.
