In 1820 Bellani invented a device for measuring evaporation that was called an atmometer. [3] Modified versions of the Bellani plate evaporimeter are still in use. [4] He invented a hygrometer using a fish bladder in 1836. Another innovation was his pyranometer to measure solar radiation which was a closed glass capsule in which alcohol was ...
A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor. [1] Humidity measurement instruments usually rely on measurements of some other quantities, such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.
In 1783, the first hair hygrometer is demonstrated by Horace-Bénédict de Saussure. In 1806, Francis Beaufort introduced his system for classifying wind speeds . [ 4 ] The April 1960 launch of the first successful weather satellite, TIROS-1 , marked the beginning of the age where weather information became available globally.
Daniel Gabriel Fahrenheit FRS (/ ˈ f ær ə n h aɪ t /; German: [ˈfaːʁn̩haɪt]; 24 May 1686 – 16 September 1736) [1] was a physicist, inventor, and scientific instrument maker, born in Poland to a family of German extraction.
Jacques Alexandre César Charles (12 November 1746 – 7 April 1823) was a French inventor, scientist, mathematician, and balloonist.Charles wrote almost nothing about mathematics, and most of what has been credited to him was due to mistaking him with another Jacques Charles (sometimes called Charles the Geometer [1]), also a member of the Paris Academy of Sciences, entering on 12 May 1785.
It was invented by Daniel Gabriel Fahrenheit (1686–1736), better known for his work in thermometry. The Nicholson hydrometer , after William Nicholson (1753-1815), is similar in design, but instead of a weighted bulb at the bottom there is a small container ("basket") into which a sample can be placed.

A thermo-hygrograph. A thermo-hygrograph or hygrothermograph is a chart recorder that measures and records both temperature and humidity (or dew point).Similar devices that record only one parameter are a thermograph for temperature and hygrograph for humidity.
