The chronometer is an instrument that accurately measures time. The first one invented was a marine chronometer, and it was created out of the necessity to have an accurate timekeeper for sea travel. John Harrison, a British clockmaker, invented this device in 1737.
The earliest thermometers were very simple in design. In 1593, an early water thermoscope was invented by Galileo Galilei. In 1612, the first crude clinical thermometer was invented by an Italian inventor Santorio Santorio. Both the thermometers were not very accurate. In 1714, Daniel Gabriel Fahrenheit invented the first modern thermometer. It was the mercury thermometer with a standardized scale.
