1890 WESTON Direct Read ELECTRICAL INSTRUMENT 125 VOLTMETER Gauge NEWARK 1st Gen

Description

An exemplar example First generation from 1890 Model 125
"Edward Weston and the Weston Electrical Instrument Company introduced the first portable and direct-reading current and voltage meters in 1888-1893. Weston's inventions enabling these meters included: the first truly permanent magnets; temperature-insensitive conductors; low-resistance and non-magnetic springs; metal coil frames where induced eddy currents provided pointer damping (1887); the electric shunt (1893) for the measurement of large currents; and multiple current ranges in a single meter."
