Pouillet Apparatus

Pouillet Apparatus

Usage conditions apply
This device, showing that the tension of vapor increases with the degree of saturation, was devised by the French physicist, Claude Pouillet (1790-1868). The “J. Salleron, Paris” inscription is that of Jules Salleron (1829-1897), an instrument maker who began in business in 1855. Used at Princeton University, it was probably purchased after the establishment of the John C. Green School of Science in 1872 and the arrival of Cyrus Fogg Brackett as professor of physics in 1873.
