Assmann Psychrometer

Description
Richard Assmann, a German meteorologist and professor at the University of Berlin, designed an "aspiration psychrometer" that used a clockwork fan to draw air past the bulbs. This example is of Soviet origin, and has an electric rather than a clockwork motor. It bears the number A735203 and N124936.
