The National Institute of Standards and Technology (NIST) exists to promote U.S. innovation and industrial competitiveness by advancing measurement science, standards, and technology. The success of their efforts is showcased in the digital archives, which contain a digital collection of the most amazing electrical (AC and DC) and electronic test and measurement devices ever built. These devices were used by the National Bureau of Standards in the early 1900s to measure resistance, capacitance, current, voltage, power, and more.
Many of the manufactures of these meters and gages were destined to become household names, such as Siemens and Halske, Leeds & Northrup, Cambridge Instrument, Stanley Electric, Weston, Western Electric Company, and many others.
The following gallery contains but a sample of the rich test and measurement history that is part of NIST.
