- Measures atmospheric pressure.
- High air pressure pushes mercury in a reservoir up a tube allowing the barometric pressure to be read
- It was invented in1643 by Evangelista Torricelli
Thermometers
- Measures temperature
- A mercury-in-glass thermometer has a bulb on the end filled with mercury that expands when heated which causes the mercury to rise allowing the temperature to be read.
- It was invented by Galileo Galilei, Cornelis Drebbel, Robert Fludd, and Santorio Santorio
