The Thermometer

Thermo comes from the Greek for "heat" and meter from the Greek for "measure".

In the mid-1600's Ferdinand II, was the first to seal the thermometer isolating it against shifts in air pressure.

In the early 1700's Daniel Fahrenheit, a German physicist devised the temperature scale and the alcohol and mercury thermometers. The centigrade scale was devised by Swedish astronomer Anders Celsius.
