Radiosonde
notes: label: Description
content: The U.S. Weather Bureau transferred this incomplete radiosonde to the Smithsonian in 1962, terming it an "original Blue Hill" instrument. The sensing elements measured temperature (bimetallic), pressure, and humidity (hair hygrometer). Transmission was controlled by a clock-driven spiral. The aneroid barometer, transmitter and battery box are missing. An inscription on the wooden board, reads "RMF 84."
