Bank of Weston cells C016 / 2041
Bank of Weston cells. These electrochemical cells produce a stable voltage used as a standard to calibrate voltmeters and define the SI unit for electromotive force (the volt). Also called a standard cell, it were invented in the USA by physicist Edward Weston in 1893. They have cadmium-mercury anodes (top of glass tube), with cathodes of liquid mercury (bottom of tubes) covered by mercury sulphate (white) and mercury. The electrolyte is a clear solution of cadmium sulphate. Weston cells provided the standard for voltage measurements between 1911 and 1990.

EDITORS COMMENTS
This print showcases the iconic Bank of Weston cells, a significant invention in the field of electricity and technology. Developed by physicist Edward Weston in 1893, these electrochemical cells were instrumental in providing a stable voltage used as a standard to calibrate voltmeters and define the SI unit for electromotive force - the volt. The image reveals an array of these historical engineering devices with their distinct features. The cadmium-mercury anodes are positioned at the top of glass tubes, while liquid mercury cathodes can be seen at the bottom, covered by layers of mercury sulphate. The electrolyte consists of a clear solution of cadmium sulphate. For nearly eight decades, from 1911 to 1990, Weston cells served as the gold standard for voltage measurements worldwide. This photograph was taken at the renowned National Physical Laboratory in Teddington, United Kingdom - an internationally recognized center for metrology and standards. Against a striking blue background, this still life composition captures not only the beauty but also highlights their technological significance. It is fascinating to witness how such early electrical apparatus paved the way for advancements in research and laboratory practices. Preserved within this image is not just history but also British ingenuity and scientific excellence that has shaped our understanding of electricity over time.
