Description
Weston Model 1031 Panel Meter 0-20 Milliamperes DC Milliammeter Round
The Weston Model 1031 is a round panel-mount DC milliammeter with a 0-20 milliampere full-scale range. It uses a moving-coil (D'Arsonval) movement — the standard mechanism for analog panel instruments — and is designed for flush panel mounting via its round flange with three mounting holes. The dial face is printed with a clear linear scale from 0 to 20 mA and is labeled "MILLIAMPERES D.C." with the Weston name. Connections are made via two rear screw terminals.

Applications
The Weston moving-coil panel meter is a classic D'Arsonval galvanometer-type instrument that has been used in electrical test equipment, laboratory benches, industrial control panels, and custom instrument builds for well over a century. The 0–20 mA range makes it well suited for monitoring low-level DC current — common in signal circuits, battery charging monitors, and process control loops where a 4–20 mA current loop signal is present. Panel meters of this type are still used today in custom enclosures, vintage equipment restoration, educational lab setups, and retro/steampunk instrument projects. Weston Electrical Instrument Corp. was one of the most respected American instrument manufacturers of the early-to-mid 20th century, headquartered in Newark, New Jersey, and their meters are known for precise movement construction and long service life. This example dates from the mid-20th century era of American panel instrument manufacturing.
This Weston Model 1031 0-20 mA DC panel milliammeter is in good used condition. The dial face is intact and legible with a cream/aged appearance consistent with its vintage. The black painted housing shows some paint chipping and wear, most visible on the rear. The moving-coil movement appears intact and the needle rests at zero. The two rear screw terminals are present and intact. This meter has not been powered or tested at our facility, but was pulled from a working environment where it was previously in use.
