In 1662, Sir Christopher Wren invented the mechanical, self-emptying, tipping bucket rain gauge. In 1714, Gabriel Fahrenheit creates a reliable scale for measuring temperature with a mercury-type thermometer. [2] In 1742, Anders Celsius, a Swedish astronomer, proposed the 'centigrade' temperature scale, the predecessor of the current Celsius ...
Fahrenheit began experimenting with mercury thermometers in 1713. [8]: 26 Also by this time, Fahrenheit was using a modified version of Rømer's scale for his thermometers which would later evolve into his own Fahrenheit scale. In 1714, Fahrenheit left Danzig for Berlin and Dresden to work closely with the glass-blowers there.

1780 – James Six invents the Six's thermometer, a thermometer that records minimum and maximum temperatures. See (Six's thermometer) 1783 – In Lavoisier's article "Reflexions sur le phlogistique", he deprecates the phlogiston theory [45] and proposes a caloric theory of heat. [46] [47] – First hair hygrometer demonstrated.
James Six FRS (1731 – 25 August 1793) was a British scientist born in Canterbury.He is noted for his invention, in 1780, of Six's thermometer, commonly known as the maximum- minimum thermometer.
Six's maximum and minimum thermometer is a registering thermometer that can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. It is used to record the extremes of temperature at a location, for instance in meteorology and horticulture .
The year 1714 in science and technology involved some significant events. Mathematics ... December 19 – John Winthrop, American astronomer (died 1779)
A maximum minimum thermometer, also known as Six's thermometer, is a thermometer which registers the maximum and minimum temperatures reached over a period of time, typically 24 hours. The original design contains mercury, but solely as a way to indicate the position of a column of alcohol whose expansion indicates the temperature; it is not a ...
