Salleron Solar Radiation Thermometer

This mercury-in-glass thermometer has a brass collar at the lower end of the tube. The milk white scale is marked “Centigrade” and “J. Salleron 24 Rue Pavee (au Marais) Paris” and carries a scale extending from -20 to +82 degrees Centigrade. The protective glass tube is marked “1 26.” It came to the Smithsonian from the U.S. Weather Bureau.
Jules Salleron began manufacturing precision instruments in 1855, moved to the address on this thermometer in 1860, and won top honors, especially for his meteorological instruments, at international exhibitions in the 1870s. Now trading as Dujardin-Salleron Laboratoires, the firm specializes in precision instruments applied to oenology.
