Description

Early 20th century (circa 1910's) Weston's Direct Reading Mil-Am-Meter - Weston Electrical Instruments Company - Model 1 No. 28074 - Newark, NJ, USA. Fan shaped metal box, wood base.

"Ammeters measure electric current, and this instrument was designed to measure direct (as opposed to alternating) current."

"The Weston Electrical Instrument Company was founded in 1888 by Edward Weston in Newark, New Jersey. Before founding the company, Edward Weston developed a saturated cadmium cell, a battery that produced a voltage stable enough to be used as a calibration standard for voltmeters. His eponymous company later went on to sell these standard cells, as well as portable test equipment. They were the first to develop accurate portable direct reading voltmeters and ammeters, and the first portable light meter." (Source: MIT Museum)
