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.
Dec 15, 2020 · Oral temperature can be taken by either a digital or mercury thermometer. We’ll go over the benefits and drawbacks of mercury thermometers below.
The three fundamental components of a thermometer are a spirit or mercury-filled liquid that reacts to temperature changes, a glass tube to hold the liquid, and black ink to fill in the engraved scale marks with legible numbers. A sensitive thermometer is required to measure temperature.
Jun 17, 2024 · Mercury containing thermometers are used in different settings, including medical, industrial, and laboratory environments. Some common domestic applications include measuring fevers, as well as oven, candy, and meat thermometers.
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.
The time-honored mercury thermometer is being phased out (because of environmental concerns), replaced by electronic thermometers with thermistors (oral, rectal, and axillary measurements) and infrared thermometers (tympanic or forehead measurements).
Mercury Thermometers. One moment while we fetch your results. Mercury-filled thermometers are instruments used to measure temperature through the expansion and contraction of the element mercury as it is heated or cooled.
Jan 11, 2023 · Once a staple in most medicine cabinets, mercury thermometers use mercury encased in glass to measure body temperature. Mercury thermometers are no longer recommended because they can break and allow mercury — which is toxic — to escape.
Dec 14, 2011 · Mercury Thermometer Alternatives. Credit: NIST. Time for replacement. For many people, the words "thermometer" and "mercury" are practically synonymous. That association is unfortunate: Mercury is a potent neurotoxin, and every thermometer that contains it is a potential environmental threat.
