EMICO RF21/4-2329 DC Milliamperes Meter 0–50mA Analog Panel Meter D'Arsonval

EMICO RF21/4-2329 DC Milliamperes Meter 0–50mA Analog Panel Meter D'Arsonval

The EMICO RF21/4-2329 is an analog DC milliampere meter designed for measuring and monitoring direct current in the 0–50 mA range. Manufactured by Electro-Mechanical Instrument Co (EMICO) of Perkasie, PA, this benchtop unit features a classic moving-coil (D'Arsonval) panel meter movement with a graduated analog scale. The meter was typical of laboratory test benches and industrial control setups from the mid-20th century onward.

Applications

DC milliamp meters of this type remain useful for troubleshooting analog circuits, verifying current draw in low-voltage DC systems, and vintage test equipment repair. Analog meters are still preferred in many laboratory and educational settings for their simplicity and ease of reading. These meters were historically used in telecommunications testing, industrial control circuits, and electronics repair benches to monitor or set precise current levels. This unit dates from an era when analog panel meters were the standard measurement tool before digital displays became common.

Condition: For Parts or Not Working
This EMICO RF21/4-2329 DC milliamp meter does not power on and is being sold as-is for parts or repair. The analog meter face and scale markings (0–50 mA) appear intact and remain legible. The aluminum enclosure shows surface oxidation, scuffing, and general age-related wear consistent with vintage surplus equipment. The unit includes the original brown cloth-covered 2-prong AC power cord. It has not been tested and is not guaranteed functional. Please view our photo set and contact us if you have any questions.
