A basic mercury thermometer is a precisely crafted piece of tube-shaped glass enveloping a mercury-filled reservoir connected to an extremely thin channel, called the capillary bore, that provides a chamber the mercury from the reservoir can expand into.
Dec 18, 2023 · In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
A mercury thermometer is a device used in scientific and clinical settings to measure temperature. It consists of a mercury-filled bulb connected to a capillary with a temperature scale, and its sensitivity is determined by the bulb volume and the coefficient of thermal expansion.
Dec 15, 2020 · Mercury thermometers provide accurate temperature readings and can be used orally, rectally, or under the arm. They don’t require batteries. Drawbacks
Apr 25, 2017 · In a thermometer, a glass bulb attached to a glass capillary tube is filled with mercury. The rest of the tube may be a vacuum, or it may be filled with nitrogen. As the mercury heats up, it rises in the tube, and as it cools, it retracts back into the bulb.
A few simple steps can help. If the liquid is not silver in color, it does not contain mercury. The non-silver liquid-in-glass thermometers typically contain a colored alcohol. Contact with the skin or inside the mouth could cause minor irritation or a burning sensation that should go away quickly.

Apr 30, 2024 · Mercury thermometers offer precision due to mercury’s unique properties, require regular maintenance for accuracy, and have alternatives like digital and bimetal thermometers for a range of temperatures.
Jan 11, 2023 · Mercury thermometers are no longer recommended because they can break and allow mercury — which is toxic — to escape. If you have a mercury thermometer, don't throw it in the trash. Contact your local trash collection program to see if there's a hazardous waste collection site in your area.
Mercury is used in a wide variety of medical devices such as thermometers, sphygmomanometers, gastrointestinal devices and dental amalgams. Considering this fact, mercury exposure is possible to all the users of the aforementioned devices.
