The Best Medical Thermometer for 2021

Here are the best medical thermometer – also called clinical thermometer:

The humble medical thermometer is one of the foremost important diagnostic tools that any medical professional (or human being) can wear hand. Temperature readings are important because an abnormally high or low temperature can help indicate many different health problems. Taken with other symptoms, abnormal temperature readings may indicate fever, infection, an allergy, hypothermia, and heat stroke, among other conditions.

The generally accepted average temperature, as taken orally, is 98.6°F (37°C). This temperature reading will vary a touch counting on what quiet thermometer you employ and what quiet reading you’re making, so you’ve got to account for that when measuring temperature. So what type of medical thermometer will get you closest to that “magical” number of 98.6°F? In this guide, we break down the six main sorts of thermometers below and explain the pros and cons of every to assist you to select the simplest medical thermometer for your needs.

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 (in the mouth), rectally (in the bottom), and axillary (under the arm). 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. The digital screen is found on the handle, which tapers right down to the probe. Medical professionals might want to take a position within the second quiet model, which is more durable and less flimsy. In these models, the probe connects to the device via a cord, and therefore the thermometer displays readouts on the massive LCD screen. Some models can also be wall-mounted, such as this Welch Allyn thermometer.

Electronic Ear Thermometer

A childhood classic, these thermometers measure temperature by sensing the infrared heat from inside the ear. They take a reading a bit faster than digital thermometers, which is why electronic ear thermometers are often used with wiggling little kids. 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

Sometimes called cerebral artery thermometers, forehead thermometers are placed against the cerebral artery within the head to live temperature. 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 (these models look quite like electric razors). The sensor can also extend out from the handle in order that it’s sort of a “gun.” These models work very quickly and typically don’t need to be placed on the skin, making them non-contact. 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. However, digital pacifier thermometers aren’t very accurate, as it’s difficult for infants to carry them still long enough to urge an accurate reading. Recommend that parents use a digital or electronic ear thermometer instead.

Plastic Fever “Strip” Thermometer

These thermometers are applied to the forehead and provides a readout on the strip by changing color. While these thermometers have some applications, they’re not very accurate and will not be utilized in medical settings.

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. In fact, the Environmental Protection Agency (EPA) is functioning to end mercury thermometers from many various industries, not just the medical field.

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 of Best Digital Thermometer

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. For older children and adults, oral readings are usually accurate – as long because the mouth is closed while the thermometer is in the situation.

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. Choose one that is scientifically tested and assures accurate results.

Which thermometer is best mercury or digital?

When used correctly, the digital thermometer is accurate enough to satisfy daily needs and safer than the mercury-in-glass thermometer, more importantly. The temperature measurement is only a reference, whether to administer medicine to children or take them to the hospital depends on the judgment of symptoms and feelings.

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

Add a touch 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. Features: Fast 8-second reading Professional Accuracy: 0.2° F in laboratory testing.


Some electronic thermometers may go by contact (the electronic sensor is placed within the location where the temperature is to be measured, and left long enough to succeed in equilibrium).

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. Although these aren’t in direct contact with the world being measured. T

They’ll still contact a part of the body (a thermometer that senses the temperature of the eardrum without touching it is inserted into the ear canal). To eliminate the danger of patient cross-infection, disposable probe covers, and single-use clinical thermometers of all kinds are utilized in clinics and hospitals.


According to a 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”

Frequently Asked Questions (FAQs) About Best Medical Thermometer

Q. What type of thermometer is used in hospitals?

Answer: Digital thermometers are considered the fastest and most accurate sort of thermometer. Readings are taken from under the tongue, from the rectum or under the armpit.

They are easily found in local pharmacies and may be used in reception or within the hospital.

Q. What thermometer do doctors use?

Answer: A thermometer is an instrument used for measuring the temperature of one’s body. The thermometer employed by doctors and nurses to live the temperature of the physical body is a mercury-in-glass clinical thermometer ( medical thermometer) starting from 35-42 degrees Centigrade.

Q. Why should a mercury-in-glass clinical thermometer not be washed in hot water?

Answer: A clinical thermometer can’t be washed with hot or very warm water because the mercury inside the thermometer will expand to pass 115 F or 120 F. Boiling water exceeds the temperature range that a clinical thermometer is designed to measure and could cause it to rupture ruining the thermometer.

Q. Who invented the doctor’s the thermometer?

Answer: The Italian physician Santorio Santorio (Sanctorius, 1561-1636) is usually credited with the invention of the primary thermometer, but its standardization was completed through the 17th and 18th centuries.

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. You can also soak things in it to disinfect them like to clean a thermometer with hydrogen peroxide (yes any type of thermometer).

Final Thoughts of Best Medical Thermometer

A medical thermometer (also called clinical thermometer) is used for measuring human or animal body temperature. The tip of the thermometer is inserted into the mouth under the tongue (oral or sub-lingual temperature)

Under the armpit (axillary temperature), into the rectum via the anus (rectal temperature), into the ear (tympanic temperature), or on the forehead (temporal temperature). The medical thermometer began as an instrument more appropriately called a water thermos-cope, constructed by Galileo Galilei circa 1592–1593.

It lacked an accurate scale with which to measure temperature and could be affected by changes in atmospheric pressure.
