An old school device that smacks a needle on to a piece of pressure sensitive paper. Currently connected to a temperature humidity sensor. The stickers seem to indicate the device was last operated in 1984, so I assume that it sat on the shelf from 84 until tonight, when I turned it on. Works, seems accurate, and responds quickly to changes in humidity. Just a neat piece of yesterday's tech.
