Quick Summary

The Weston cell, also known as a cadmium cell, is a type of voltaic cell used as a standard for electromotive force. It was patented in 1893 by Edward Weston, a British-born American electrical engineer and industrialist. Weston was known for his work in electrical measuring instruments and founded the Weston Electrical Instrument Company. The cadmium cell is a specific type of Weston cell.123

434 volts) and the Weston cell (cadmium–mercurous sulfate–mercury; 1.019 volts). Magnesium–silver chloride and magnesium–lead chloride batteries are commonly employed in undersea operations where the salt water becomes the electrolyte when the battery is submerged or in situations where low risk to the environment is desired, as in balloon batteries.

…units was based on high-stability Weston cadmium cells. These cells, however, tend to drift and so caused inconsistencies between standards in different laboratories. The Josephson method has provided a standard giving agreement to within a few parts in 10⁸ for measurements made at different times and in different laboratories.
