What is the history of a hygrometer?
In the 15th century Leanardo da Vinci built the very fist hygrometer. Francesco Folli invented a more practical hygrometer in 1664. In 1783 Horace Benedict de Sausser built the first hair hygrometer. John Frederic Daniell invented a dew-point hygrometer in 1820. Hair hygrometers weren't in regular use until the 1960s.
