Aspiration Psychrometer

notes: label: Description
content: In the late 1880s, a German meteorologist named Adolph Richard Assmann designed an aspiration instrument which used a fan to draw air past the wet- and dry-bulb thermometers of a common psychrometer. Assmann also enclosed the device in double-walled ducts of polished metal designed to minimize the effect of radiation. This form would long remain in widespread use. This example was made in Russia, and is marked "OCTN 40083 N 103157 1941 r."
