notes: label: Description
content: In the 1770s, scientists developed eudiometers for determining the goodness (or rather, the oxygen content) content of samples of air. The most successful form, described by Alessandro Volta in 1777, used an electric spark to ignite the air to be tested.
label: Description
content: Building on Volta’s work, the American chemist, Robert Hare (1781–1858), developed an “aqueous sliding-rod hydro-oxygen eudiometer.” This replica of Hare’s instrument was made in anticipation of the opening of the National Museum of History and Technology in 1964.
