What is Medical Thermometer

A medical thermometer is a device used to measure the body temperature of a human or an animal. It is a crucial tool in diagnosing and monitoring medical conditions such as fever, infections, and other illnesses. Medical thermometers are designed to provide accurate readings of body temperature in various ways, including orally, rectally, under the armpit, or on the forehead.

Traditional thermometers consist of a glass or plastic tube with a thin, sealed, mercury or alcohol-filled bulb at one end and a calibrated scale on the other end. Digital thermometers, on the other hand, use electronic sensors to detect and display temperature readings digitally. Some modern digital thermometers even come with additional features such as fever alarms, memory functions, and Bluetooth connectivity to record and monitor temperature readings over time.

It is essential to use a thermometer specifically designed for medical purposes to ensure accurate and safe readings. Proper cleaning and sterilization of the thermometer after each use are also necessary to prevent the spread of infections.

Digital Thermometer

The fastest and most accurate option, these thermometers take your temperature through a metal probe and display temperature readings on a digital screen.

A digital thermometer can take your temperature in three ways: orally, rectally, and axillary. This should go without saying, but don’t use an equivalent digital thermometer to require temperatures rectally and orally.

There are two main models of digital thermometers. The first is a cheap but less sturdy single-piece design. Medical professionals might want to take a position within the second quiet model, which is more durable and less flimsy.

Electronic Ear Thermometer

A childhood classic, these thermometers measure temperature by sensing the infrared heat from inside the ear. However, ear thermometers might not deliver accurate results for little babies three months old or less due to their very small, curved ear canals.

Also, if the patient has ear wax, which will affect the reading and cause an inaccurate temperature.

Forehead Thermometer

Somewhat like electronic ear thermometers, they take a temperature reading by measuring the infrared heat coming off the cerebral artery. Forehead thermometers may integrate the sensor into the handle.

However, they don’t usually deliver as accurate a reading as taking the temperature orally or rectally.

Digital Pacifier Thermometers

Some parents use these thermometers to require temperature readings in small infants without their knowing it. Recommend that parents use a digital or electronic ear thermometer instead.

Glass and Mercury Thermometer

The original medical thermometer design, glass, and mercury thermometers have fallen out of recognition with the increase of digital technology. The glass housing meant that the thermometers were breakable, which wasn’t ideal since mercury is toxic.

If you continue to own a mercury-in-glass thermometer, don’t just throw it into the trash. Instead, research hazardous waste disposal options in your area. Choosing a medical thermometer are often an inexpensive, quick purchase or an enormous investment.

Buying Guide

Which type of thermometer is the most accurate?

Armpit temperatures are usually the least accurate. Rectal temperatures provide the simplest readings for infants, especially those 3 months or younger, also as children up to age 3.

How do I choose a thermometer?

An all-important factor while choosing a thermometer is its ability to provide accurate readings. You don’t want to risk it when it comes to dealing with body temperature and the potentially serious consequences it may have.

How do I do know if my digital thermometer is accurate?

Add a touch of clean water until the glass is full and stir. Wait for about three minutes before inserting the sensor on the thermometer into the ice-filled water.

Wait for about thirty seconds and make sure the thermometer reads 32°F. If it does, then it’s accurate, but if not, it requires calibration.

Are Vicks digital thermometers accurate?

The Vicks Speed-read Digital Thermometer with a large screen display and Fever Insight feature makes taking temperature fast, easy, and comfortable.


Some electronic thermometers may go by contact. These typically reach equilibrium faster than mercury thermometers; the thermometer may beep when equilibrium has been reached, or the time could also be laid out in the manufacturer’s documentation.


Other electronic thermometers work by remote sensing: an infrared sensor responds to the radiation spectrum emitted from the situation.


According to 2001 research, electronic thermometers on the market significantly underestimate higher temperatures and overestimate lower temperatures.

The researchers conclude that “the current generation of electronic, digital clinical thermometers, generally, might not be sufficiently accurate or reliable to exchange the normal glass/mercury thermometers”


Q. Is a thermometer A medical device?

Answer: A thermometer is a medical device if its purpose is to take people’s temperature. However, if you sell it to take air temperatures, it is not a medical device. The Internet is not a medical device, since the intended use is to transmit data without modifying it.

Q. Will hydrogen peroxide disinfect a thermometer?

Answer: Besides cleaning, peroxide is often wont to disinfect items around your home. Just spray it on, allow the bubbles to subside, and repeat.

Final Thoughts

A medical thermometer is used for measuring human or animal body temperature. The tip of the thermometer is inserted into the mouth under the tongue.

The medical thermometer began as an instrument more appropriately called a water thermos-cope, constructed by Galileo Galilei circa 1592–1593.
