Why do thermometers that measure infrared emission from the eardrum work so well?

They work so well because the eardrum is a good location for measuring heat that is released from the body's main temperature control center, the hypothalamus. These thermometers use thermal radiation and never have to come in actual direct contact with the source of heat.

What are the four different kinds of thermometers?
Types of Thermometers - ApplicationsClinical ThermometersThe 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) thermometersHuman 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 fragile and delicate body part. Therefore, the body temperature cannot be measured by touching the eardrum. For temperature measurement, infrared sensors are used to remotely sense the temperature of the eardrum. Thermopile, an infrared sensor, is commonly used in ear thermometer.Pacifier ThermometersThe pacifier thermometers are used to check the body temperature of babies or infants. They help measure the body temperature without irritating the baby. The thermometer is held in the mouth of the baby and the baby's natural sucking instinct is used to check its body temperature. The pacifier thermometers are very safe for checking the body temperature of babies.Underarm or Oral ThermometersThe underarm thermometers are kept in the underarms to measure the body temperature of the patient. Likewise, the oral thermometers are held in the mouth for temperature measurement.
What is an infrared laser thermometer used to measure?
An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called blackbody radiation emitted by the object being measured. They are sometimes called laser thermometers if a laser is used to help aim the thermometer, or non-contact thermometers to describe the device's ability to measure temperature from a distance. By knowing the amount of infrared energy emitted by the object and its emissivity, the object's temperature can often be determined. Infrared thermometers are a subset of devices known as "thermal radiation thermometers".
What is the difference between digital and mercury thermometer?
Digital thermometers measure electrical resistance and Mercury thermometers measure thermal expansion.
What are mercury thermometers used to measure?
Thermometers of any kind measure one thing: temperature.
The thermometers doctors use to measure our body is called?
Doctors use body temperature thermometers to measure body temperature.
Do thermometers measure in Celsius?
Some do.
How can you measure Fahrenheit and Celsius?
With thermometers
What is the instrument to measure the function of the eardrum?
tympanometer
When is it important to use a non contact thermometer?
A non contact thermometer should be used when a quick temperature measurement is required. Non contact thermometers depend on infrared technology to measure the surface temperature of an object.
