Weston 430 Vintage DC Voltmeter 0-500V 5000 Ohms/Volt 10 100 500V Taps

Weston 430 Vintage DC Voltmeter 0-500V 5000 Ohms/Volt 10 100 500V Taps

The Weston Model 430 is a portable analog DC voltmeter built around a high-sensitivity D'Arsonval moving-coil movement. It offers three selectable voltage ranges via top-mounted terminal posts, covering low-voltage signal work through mains-level DC measurements up to 500 volts. With a sensitivity of 5000 ohms per volt, it draws minimal current from the circuit under test — a meaningful advantage in the era before solid-state electronic instruments. This unit was manufactured for The Seeburg Corp as engineering equipment (Type E6053-000) and has been tested by our staff to read correctly on all three taps.

Applications

Weston was one of the most respected names in electrical measurement from the late 19th century through the mid-20th century, and the Model 430 represents the classic portable panel meter design that was standard in engineering labs, radio stations, power plants, and industrial test benches from roughly the 1930s through the 1960s. DC voltmeters of this type were used to check battery voltages, generator outputs, rectifier circuits, and power supply rails in an era when transistors and integrated circuits were just emerging. The 5000-ohm-per-volt sensitivity rating places this instrument in the mid-tier of the analog voltmeter world — sensitive enough for most power-circuit work, and far more robust than the fragile high-sensitivity galvanometer-based instruments of the same era. Today, instruments like this are sought by vintage electronics restorers, ham radio operators working on tube-era gear, collectors of scientific instruments, and anyone who needs a reliable high-voltage DC meter for classic equipment servicing. The Bakelite housing and leather handle are characteristic of the portable bench instruments produced through the late 1950s.
