Mercury Thermometer
Mercury Thermometer (also known as mercury-in-glass thermometer) was invented by German physicist Daniel Gabriel Fahrenheit in 1714. Mercury Thermometer is actually a thermometer in a glass tube. The mercury in the glass tube varies (nearly linearly) according to the temperature of the mercury and calibrated marks on the tube allow the temperature to be read by the length of the mercury within the tube. At the end of the tube is generally a bulb of mercury which contains most of the mercury. The expansion and contraction of this volume of mercury in the bulb is then amplified in the much narrower bore of the tube. The space above the mercury is then filled with nitrogen or it may be less than atmospheric pressure, which is normally a vacuum.

The bulb at the end of mercury thermometer looks silver. If the bulb is red, blue, purple, green or any other color, it is not a mercury thermometer.

Mercury thermometers are used to measure body temperature (fever thermometers), liquid temperature, and vapor temperature.
