Types of Thermometer and Their Accuracy
There are various types of thermometers used in the medical field. Let us examine some of them today. Digital Touch Thermometer Digital touch thermometers determine body temperature using heat sensors. We can use them orally, under the armpits, or up the rectum. Note that taking oral temperatures as the base, such a digital thermometer gives a reading half a degree lower in the armpits and half a degree higher in the rectum when measured in Celsius. They give accurate readings in less than a minute. Oral Thermometer Oral thermometers are those that work only when placed in the mouth under the tongue. They can be both digital and analog (mercury). The average body temperature varies from 36.1 to 37.2 degrees Celsius.
