The usually accepted average temperature, as taken orally, is 98.6°F (37°C). This temperature reading will differ a touch depending on what silence thermometer you employ and what quiet reading you’re making, so you have to account for that when measuring temperature.

What is a 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 babies three months old or less due to their very small, curved ear canals.

Also, if the patient has ear wax, it 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 is often an inexpensive, quick purchase or an enormous investment.

Buying Guide

I’d be happy to guide you through selecting a medical thermometer! Here are some key factors to consider when purchasing one:

Types of Thermometers

1. Digital Thermometers

Oral/Rectal/Axillary: Typically used for oral, rectal, or underarm measurements. They are accurate and easy to read.

Temporal Artery (Forehead) Thermometers: Scan the temporal artery in the forehead for quick readings. They’re non-invasive and suitable for all ages.

Ear (Tympanic) Thermometers: Measure the temperature inside the ear canal. Quick and generally accurate, but technique-dependent for accuracy.

2. Infrared Thermometers

Non-Contact: Measure temperature without touching the body. Great for quick readings and use on children.

Factors to Consider

1. Accuracy

Look for thermometers with high accuracy. Medical-grade thermometers tend to be more reliable.

2. Speed

Quick readings are important, especially for restless or unwell individuals. Infrared and digital options often provide faster results.

3. Ease of Use

Consider the readability of the display, ease of cleaning, and how user-friendly the thermometer is.

4. Memory and Additional Features

Some thermometers store previous readings, which can help track temperature changes. Other features might include fever alerts or compatibility with apps for data tracking.

5. Age Appropriateness

Ensure the thermometer is suitable for the intended age group (infants, children, adults).

6. Hygiene and Maintenance

Thermometers need to be cleaned after each use to prevent cross-contamination. Consider ease of cleaning when choosing a thermometer.
