notes: label: Description
content: In the late 1880s, a German meteorologist named Adolph Richard Assmann designed an aspiration instrument with 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 remained in widespread use for many years.
