Antique Weston A.C. Voltmeter model 155 Weston Electrical Instrument Co. Newark, N.J. U.S.A.
The Weston Electrical Instrument Company was founded by Edward Weston. Weston is most known for his designs and the manufacturing of precision electrical measuring instruments for laboratories and industry.
Born in England in 1850, Edward Weston attended medical school and became a chemist. He then moved to the United States and made advances in electroplating, power generation, and the electric light. In 1888 he formed The Weston Electrical Instrument Company and developed an instrument to accurately measure current. From there, Weston Electrical Instruments went on to manufacture precision voltmeters, ammeters, watt meters, light meters, and many other instruments for laboratory, industrial, and commercial use.

Notes | Portable AC Voltmeter Single Range 125 V. But see the different versions - with different scales and other differences - all with the model type 155! Last patents are from 1898. We need advertisements and other documents to be able to tell the starting date which could have been as early as 1898 but was probably a year or a few years later. The different versions show a long manufacture time of decades. |
