The 6 Best Infrared Forehead Thermometers (Wands)

A high-quality infrared (no touch) forehead thermometer can give you instant readings and is the quickest and most convenient device for checking for fever in any baby, child, or adult.

But:

Are forehead thermometers accurate? Which one is best for your needs?

We set out to find the most accurate, consistent, fast, and easy-to-read forehead (temporal artery) thermometers of 2025.

Here’s a short comparison, followed by our temperature wand reviews:

Forehead Thermometer Accuracy

Temporal artery thermometers, known as forehead thermometers, use an infrared scanner to measure the temperature of the temporal artery in the forehead.

The latest research suggests that forehead infrared thermometers are the most accurate alternative to rectal digital thermometers for taking a child’s body temperature.

However, the environment around you may influence your skin temperature.

If you want an accurate read, the tested child or adult needs to be in the same room for 30 minutes, and the forehead area needs to be clean and dry. 

Infrared thermometers can skim a person’s temperature, are easy to use, safe, and easily tolerated by children and babies.

With some thermometers, you don’t even have to touch the skin to read the temperature, which makes them best for testing sleeping children without waking them up and disturbing them.

They are the best fit for babies older than 3 months and children, and according to the Mayo Clinic, new research suggests that they may also be used for newborns.

Do You Need to Add a Degree with a Forehead Thermometer?

User manuals report an accuracy of about 0.4 Fahrenheit degrees, which is not ideal, but all the accuracy in the world won’t help if you can’t use it on a temperamental child.

A forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

What is Considered a Fever When Using a Forehead Thermometer?

According to the Seattle Children’s Hospital, a forehead temperature of 100.4° F (38.0° C) or higher is considered a fever in both children and adults.

Checking for fever can be done in different parts of your body, including the armpit, mouth, ear canal, rectum, and forehead.

• An ear temp. is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature.
• An armpit (axillary) temperature is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.
• A forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

The 6 Best Infrared (No Contact) Forehead Thermometers 

Our requirements for a forehead thermometer were simple: something fast, accurate, consistent, silent, and easy to read.

Here are the most accurate forehead thermometers of 2025:

1. Braun No Touch Forehead Thermometer – Most Silent

The Braun No Touch thermometer offers a completely silent reading (best for sleeping children/babies) and speedy and reliable readings, thanks to the age and fever guidance built-in feature.

You simply turn it on, select the age range, position it up to 2 inches away from the point between the eyebrows, and press the temperature button when the 3 dashed lines appear.

(The gentle guidance light directs you to accurate aiming)

When the infrared scanner is done (in 2 seconds!), you’ll see the appropriate fever light glow (green/yellow/red) to help you understand the temperature reading.

Braun No Touch Thermometer Pros

How to Use a Forehead Thermometer

If you have a no-touch forehead thermometer, you simply turn it on, position the device in the center area between the eyebrows, at a 2.5 cm (1 inch) distance, and press the button to take a reading.

Hold the thermometer in place until it beeps or otherwise indicates that the reading is done.

Read the temperature on the display, then turn it off and clean it according to the instructions.

With a contact forehead thermometer, you’ll need to slowly slide the thermometer across the forehead toward the top of the ear, until the device indicates the reading is done.

Are Temperature Wands Safe?

Infrared temperature wands do not emit any kind of electromagnetic radiation, they only measure infrared heat to determine your temperature.

The red beam coming out of the thermometer is visible and harmless and is made to guide the person taking your temperature to the right spot – for an accurate read.

There is no evidence of any side effects or risk of using a forehead thermometer, which allows for a quick, non-contact, and easy way to read your body temperature. For more information, see this post.

Ear Thermometer vs. Forehead Thermometer – Which Is Better?

Ear thermometers, also known as tympanic thermometers, measure the body’s temperature through the eardrum and surrounding tissue.

Some studies have found them more accurate than forehead thermometers, but they can be more difficult to use, especially with babies, toddlers, and people with small ear canals.

I would use an ear thermometer only for children over 6 years old who may not resist feeling the probe in their ears and definitely would not use them for children and adults who are sleeping.

Mercury vs. Digital vs. Infrared Thermometers

Accuracy – Mercury thermometers are considered highly accurate, serving as a standard reference for many years.

Digital thermometers are also known for their accuracy and precision.

Infrared forehead thermometers can be less accurate due to external factors like sweat or environmental temperature affecting the skin temperature.

Speed – Mercury thermometers take the longest time to provide a reading as the mercury needs to expand and contract with temperature changes.

Digital thermometers are much faster, providing readings within seconds.

Infrared thermometers are the fastest, offering almost instant readings.

Ease of Use – Mercury thermometers require proper handling and reading of a small scale, which can be challenging for some people.

Digital thermometers are user-friendly with clear digital displays.

Infrared thermometers are the easiest to use, often requiring just a simple point-and-click.

Price – Mercury thermometers are generally the cheapest, but their use is declining due to the toxic nature of mercury and environmental concerns.

Digital thermometers are affordable and widely available.

Infrared thermometers tend to be more expensive due to their advanced technology and the convenience of non-contact use.
