All thermometers are designed to give you an accurate reading; however, if you want a thermometer that is easy to use, especially on young children, then a temporal thermometer is highly recommended.

Temporal Thermometer uses infrared light to measure the temperature of the temporal artery located in the forehead. and is completely non-invasive and can also be applied when the patient is sleeping, making it ideal for babies and small children.

Here we’ll show you how to use temporal thermometer in few easy steps so that you and your family can stay safe in this pandemic.

Proper Steps for Taking Temperature with Temporal Thermometer 

Here’s the step-by-step guide on taking the temperature with the help of a temporal thermometer.

Step 1: Make Sure the Probe Is Clean

First of all, check whether the probe is clear or not. The probe needs to be clean to take an accurate reading of the temperature. A temporal thermometer uses infrared light rays to measure the temperature. So, if there is dirt blocking or disrupting the light, the reading will be inaccurate.

The thermometer does come with a cover to protect it from dust, but you can easily clean the probe by rubbing it with alcohol wipes or with q tips dipped in a little bit of rubbing alcohol and letting the probe dry afterward.

Additionally, place the thermometer upside-down to prevent excess moisture from entering the sensor area as if it becomes too wet, it won’t be able to take a temperature until it dries.

Step 2: Brush Hair Covering the Forehead and Ear Away

To take the temperature you need to have access to your forehead and at the back of your earlobes. So, if you have hair on these areas then the thermometer might not be able to give accurate readings. Again, anything blocking or disturbing the infrared light will lead to false temperature readings.

So, before you measure your temperature make sure to brush off all the hair from the forehead and at the back of the earlobes.

Step 3: Place Probe Flush on the Forehead and Press the Button

You need to place the probe of the thermometer flush at the center of your forehead (about 1 inch or 2-3cm from your hairline) to make so that the infrared light gets a proper reading of the temperature. After that, you need to press the button and keep pressing it until the temperature checking process is done.

How to Use Temporal Thermometer

During this step please Do NOT let go of the button as it is required to measure the temperature.

Step 4: Slide STRAIGHT across Forehead to the Temporal Area

This is the most important step in this process.

After putting the probe flush on your forehead and pressing the button you need to drag the probe across your forehead to the temporal artery area and stop your slide when you have reached the hairline of your ear.

During this step please Do NOT move the thermometer down the slide of your face after dragging the probe across your forehead as you could miss the temporal artery and decrease the accuracy of your result.

Step 5: Lift Probe from Forehead and Touch Just Behind the Ear Lobe.

After dragging the thermometer across the forehead, remove it from the forehead and place the thermometer at the back of your earlobe. By doing this you will be able to give the thermometer all the information it needs to read your body temperature.

Step 6: Remove, Read and Record Temperature

The last step is to slowly remove the thermometer from your ear lobe and let go of the button. This will stop the temperature reading process and the thermometer will show the body temperature.

Normal body temperature ranges around 94° F / 34.5° C and the thermometer can give readings from 94° to 110°F (34.5° to 43°C).

Alternative Areas to Use Temporal Thermometer

Like other thermometers, temporal thermometers can also be used in other areas to measure your body temperature.

Alternative Areas to Use Temporal Thermometer

The thermometer determines the temperature by measuring the heat on the surface of the skin, which results from blood moving through the artery. This indicates it does not necessarily have to be the temporal artery.

Other areas where a temporal thermometer can be used are:

Femoral Artery

It is one of the major arteries of the human body that carries blood to the lower section of the body. To scan your temperature just slowly slide the probe across the groin where the femoral artery is located.

Lateral Thoracic Artery

This artery is in the chest area of your body. You can measure your temperature here by slowly scanning side to side in the area midway between the axilla/underarm and the nipple.


The axilla is located under the joint where the arm connects to the shoulder. Place the probe in your axilla for 2-3 seconds to measure your body temperature.

Final Words

When your child is sick, it is of absolute importance to determine the temperature. The best way to do this is by using a temporal thermometer.

To learn how to use a temporal thermometer, follow the instructions mentioned in this article and avoid the mishaps of getting inaccurate results. Stay safe.
