Why do astronauts use ear thermometers?
so they don't stay out in space, out of space craft for too long otherwise they will get hypothermia and frostbite.
An aural (in ear) thermometer is a good modern device, and measures the temperature in the outer ear. It is more expensive than a mercury clinical thermometer, but is simpler to prepare between patients, and completely avoids the problems of broken glass thermometers, and spilt mercury. Mercury clinical thermometers are however quite cheap.
Types of Thermometers - Applications Clinical Thermometers The clinical thermometers are used to measure the body temperature of the patient. There are again three types of clinical thermometers depending on the body part used to measure the temperature. Ear (Tympanic) thermometers Human ear is located near the brain. This makes it an accurate point to measure the body temperature. The temperature of the eardrum is measured by the ear thermometers. However, the eardrum is most…

There are several types of thermometers. Clinical thermometers are used to measure the body temperature of the patient. Ear Thermometers make it an accurate point to measure the body temperature. Pacifier thermometers are used to check the body temperature of babies or infants. Underarm thermometers are kept in the underarms to measure the body temperature. Not to mention the food thermometers that are often used for checking the heat of the oil or pop up…
When mercury filled thermometers break, the mercury is released. Mercury is toxic to people, pets and the environment. There is a long history of mercury from broken thermometers and other medical devices being improperly dealt with, or even ignored. Since there are adequate replacements for mercury thermometers, OSHA, EPA, AMA and others discourage the use of mercury thermometers and encourage their replacement with thermometers using other technologies.
Thermometers used to have mercury in them because it is very temperature reactive and a liquid across most temperatures measured in everyday life. However, this practice has been discontinued due to the health risks associated with contact with mercury from broken thermometers; most analog thermometers today use colored ethanol as the measuring fluid.
Whether the body temperature can be measured by keeping the thermometer at some place other than mouth?
Contributed by 1st grader Mackenzie and her mom Julie: There are circle thermometers which are like a clock and you read the numbers from left to right. There are stick thermometers that go under your tongue, your arm pit or other body parts. The numbers go from bottom to top. There are digital thermometers that can go in your ear, on your finger or other body parts. There are inside thermometers and outside thermometers to…
