  • Mercury/alcohol thermometer: The traditional thermometer makes use of mercury or colored alcohol hermetically sealed inside a glass tube. When inserted under the tongue, in the armpit or inside the rectum, the heat from the body causes the mercury or alcohol to expand and rise up the graduated tube. The advantages of these types of thermometers is that they are cheap, easy to read, can be submerged in liquids, require very little maintenance and are reliable. The disadvantages are that they break easily and there is risk of mercury poisoning if the glass tube breaks.

  • Digital thermometer: A digital thermometer uses electronic heat sensors and displays the reading digitally on a small LCD screen located on one side of its broader end. Just like the mercury/alcohol thermometer, it is inserted under the tongue or in the armpit or inside the rectum to measure body temperature. The advantages of digital thermometers are that they are inexpensive, easy to read, require very little maintenance and give an accurate reading. The disadvantage is that they get damaged easily if dropped and the battery powering them eventually runs out.
