 How Does the Thermometer Work?   (Site not responding. Last check: 2007-11-07)
One of the earliest inventors of a thermometer was probably Galileo.
Early thermometers used water, but because water freezes there was no way to measure temperatures less than the freezing point of water.
Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold.

  Thermometer - MSN Encarta
The modern alcohol and mercury thermometers were invented by the German physicist Gabriel Fahrenheit, who also proposed the first widely adopted temperature scale, named after him, in which 32° F is the freezing point of water and 212° F is its boiling point at standard atmospheric pressure.
A mercury-in-glass clinical thermometer, for example, is a maximum-reading instrument in which a trap in the capillary tube between the bulb and the bottom of the capillary permits the mercury to expand with increasing temperature, but prevents it from flowing back unless it is forced back by vigorous shaking.
In measuring the air temperature outside a building, for example, if one thermometer is placed in the shade and one in the sun, only a few centimeters away, the readings on the two instruments may be quite different, although the air temperature is the same.

 Thermometer Summary
A gas thermometer has the column filled with gas at a low pressure and there is a weight at the top of the column to maintain a constant pressure.
Réaumur's thermometer was remarkable in that he devised an 80-degree temperature scale based upon the freezing and boiling points of water--the same points that, years later, would become the basis for the more widely accepted scales of Celsius and Fahrenheit.
Thermometers may be low-cost models that may be found in a medicine cabinet, or high-tech models used in research and engineering.

 Linné on line - Linnaeus' thermometer
The second thermometer arrived in good condition in the garden in November 1745, and Linnaeus notes in his letter of thanks to Elvius that it was "very well made indeed." Somewhat later, on December 2, 1745, a proud Linnaeus could demonstrate it to the University Board.
The thermometer was a success among the learned gentlemen and the purchase of the instrument was approved.
The thermometer we use today is thus what you might call a "Linnaeus-thermometer." In its growing triumphal progress throughout the world it has been called Celsius-novum or just the Swedish thermometer and in our days the Celsius thermometer.

 Appliance Thermometers
Appliance thermometers are specially designed to measure the temperature of the air in either the refrigerator/freezer or the oven.
Other refrigerator thermometers, and most oven thermometers, are designed to hang from a wire rack or sit on a shelf.
These thermometers can measure temperatures from 100 to 600°F. To check the accuracy of an oven, hang the oven thermometer from a rack in the center of the oven (you may have to adjust the oven racks).

 Infrared Thermometer - OMEGA
As such, the infrared thermometer is useful for measuring temperature under circumstances where thermocouples or other probe type sensors cannot be used or do not produce accurate data for a variety of reasons.
Some typical circumstances are where the object to be measured is moving; where the object is surrounded by an EM field, as in induction heating; where the object is contained in a vacuum or other controlled atmosphere; or in applications where a fast response is required.
This technique is not dissimilar to the infrared thermometers described so far, but measures the ratio of infrared energy emitted from the material at two wavelengths, rather than the absolute energy at one wavelength or wave band.

 Proper Food Thermometer Placement
When cooking whole poultry, the food thermometer should be inserted into the thickest part of the thigh (avoiding the bone).
However, if using an "instant-read" dial bimetallic-coil food thermometer, the probe must be inserted in the side of the food so that entire sensing area (usually 2-3 inches) is positioned through the center of the food.
To avoid burning fingers, it may be helpful to remove the food from the heat source (if cooking on a grill or in a frying pan) and insert the food thermometer sideways after placing the item on a clean spatula or plate.

 Howstuffworks "How does a Galileo thermometer work?"
Based on a thermoscope invented by Galileo Galilei in the early 1600s, the thermometer on your co-worker's desk is called a Galileo thermometer.
The Galileo thermometer consists of a sealed glass tube that is filled with water and several floating bubbles.
The basic idea is that as the temperature of the air outside the thermometer changes, so does the temperature of the water surrounding the bubbles.

 Cooking Thermometer, Meat Thermometer, Cooking Measurement, Using A Cooking or Meat Thermometer
Cooking thermometers take the guesswork out of cooking, as they measures the internal temperature of your cooked meat and poultry, or any casseroles, to assure that a safe temperature has been reached, harmful bacteria have been destroyed, and your food is cook perfectly.
The sensing area of thermometers is ½ inch to 2 inches long, and this area must be completely immersed in the deepest area of the food.
Some dial thermometers have a calibration nut under the dial that can be adjusted by twisting the small nut beneath the thermometer face with pliers.

When air molecules collide with a thermometer, kinetic energy is transferred from the air molecules to the glass and then to the mercury molecules inside the thermometer.
In colder air, the energy from the air molecules colliding with the thermometer transferring to the mercury molecules is less than the energy from warmer air.
As a result, the mercury molecules move slower in the colder air and the mercury inside the thermometer does not expand as far up the tube as it does in the warmer air.

 The Thermometer
WEBSTER'S DICTIONARY: Thermometer: An instrument for determining temperature consisting typically of a glass bulb attached to a fine tube of glass with a numbered scale and containing a liquid (as mercury or colored alcohol) that is sealed in and rises and falls with changes of temperature.
The early bulb thermometers relied upon the principal that liquids change volume relative to temperature.
If you are using an *inaccurate* thermometer, you may be cooking for long periods of time at temperatures in excess of 260-270 degrees or possibly even less than 200 degrees.
