A temperature-control box for saturated standard cells
E.F. Mueller, Harold F. Stimson · Journal of research of the National Bureau of Standards · 1934
In order to meet the need for a portable standard of electromotive force some- what better than the unsaturated standard cell, a semiportable temperature- control box for a group of saturated cells was constructed, and is described here.The apparatus provides an adequate solution for the problem of maintaining a working standard of emf for those purposes for which the unsaturated cell is not good enough.
