Description
General Electric GE DP-9 8DP9VED1 DC Millivolt Voltmeter 0-150mV Analog Meter
The General Electric DP-9 (part number 8DP9VED1) is a vintage portable DC millivolt voltmeter with a dual-range analog movement, covering 0–15mV and 0–150mV full-scale. Made in the USA by General Electric, this instrument uses a D'Arsonval moving-coil meter movement housed in a rugged black clamshell case with an integrated carry strap, making it well suited for bench and field measurement of low-level DC voltages.

Applications
DC millivolt meters of this type are used to measure small direct-current voltage signals that fall below the range of standard voltmeters. The GE DP-9 was designed for use in laboratory, industrial process control, and calibration applications where precise low-level DC measurement is required — for example, reading thermocouple output, verifying small signal levels from transducers or bridge circuits, and calibrating other instruments. General Electric produced instruments of this class primarily from the 1940s through the 1960s, and the DP-9's portable clamshell format made it common in field service kits alongside laboratory benches. Vintage GE millivolt meters are still sought by technicians working with legacy industrial instrumentation and by collectors of classic American electrical test equipment. The dual-range design — switching between 15mV and 150mV full scale — allows a single instrument to handle both very low-level signals and somewhat higher millivolt measurements without an external shunt or multiplier.
This General Electric DP-9 DC Millivolt Voltmeter (Model 8DP9VED1) has been inspected and is in good used condition. It was pulled from a working environment where it was in active use. The black clamshell case is intact with the carry strap attached; the case shows light scuffing and surface wear consistent with age and field use. The meter face and scale are clean and legible, with the needle and analog movement appearing intact. The three binding posts (positive, 15MV, 150MV) are visible and in good shape.
