    This 150-mv Weston Model 1 millivoltmeter serial No. 12, 797 was purchased in 1908 for general laboratory use. It is an early example of the type of permanent-magnet moving-coil DC indicating instrument invented by Edward Weston around 1888. Though based in principle on the earlier work of d'Arsonval, the particular choices of dimensions and materials made by Weston were so sound that this basic design has persisted with only minor improvements for many decades.8 x 17 x 15 c

    One of the many electrical engineering machines from Weston Electrical Instrument Co. The company was founded by Edward Weston, in 1888, in Newark. Weston was an early competitor of Thomas Edison in electric light but then turned toward innovations in electrical measurement instruments, gaining prominence in scientific and engineering fields. He was also one of the founders of the Newark Technical School, which became NJIT. Weston Hall is named after him and his son, Edward Faraday Weston. In 2016, Weston’s meters were awarded an IEEE Milestone, the plaque for which is viewable inside the NJIT Electrical and Computer Engineering Department. This voltmeter is used for measuring volts, the differences of potential between points of an electrical circuit.https://digitalcommons.njit.edu/instruments/1025/thumbnail.jp
