How to choose the thermometer for you

Choose the right thermometer for you
Types of Thermometer

Mercury glass thermometers, although difficult to read, have been used for years to measure rectal, oral or axillary (but not ear-like) body temperature. They are no longer recommended because they can easily break and release mercury, which is toxic.

Digital electronic thermometers offer many advantages over glass thermometers; temperature measurements are quicker and the digital display is easier to read. In addition, they do not pose a risk of injury due to glass breakage or mercury leakage.

Infrared thermometers measure the heat generated by surfaces and cavities. The main advantage of this type of thermometer is their speed; it takes just a few seconds to measure the temperature.

The infrared ear thermometers measure the heat emitted by the tympanum and the surrounding tissues. They provide a precise reading on an easy-to-read digital display in just a few seconds. The most recommended ear thermometer is Braun ThermoScan®. *

The front infrared thermometers measure the temperature on the forehead in a gentle way. The front thermometers measure the infrared energy emitted from the skin above the eyebrow area and the surrounding tissues.

This energy is collected through the lens and converted to a temperature value. Thermometer accuracy depends on the type of technology used. The front thermometers can measure the temperature in contact with the forehead or at a distance.

The Braun Thermometer No frontal touch is the first and only thermometer to measure temperature in both touch and no touch mode with clinically tested accuracy.

How to Measure Temperature

The most common methods for measuring the temperature are ear (ear), oral (in the mouth), rectal (in the anus), axillary (under the armpit) or frontal (on the forehead). Each method is considered accurate, if performed correctly. Temperature measurements may vary slightly depending on the method, so always use the same method to achieve consistent results.


Earphone temperature measurement is a gentle, easy and quick method and is therefore preferred by many parents. However, the temperature often varies between measurements, causing doubt that the ear thermometers are not accurate. To minimize this effect, it is very important to use the correct ear thermometer. Look for a thermometer with a small preheated tip and positioning guide to ensure accurate measurements.
As with any thermometer, make sure the baby is comfortable before measuring the body temperature and following the instructions of the manufacturer. Headphone measurement only takes a few seconds.

When measuring the temperature with a headphone thermometer you should pay attention to the following:

Always measure the temperature in the same ear, as the measurements can change from ear to ear.
Some external factors may affect earphone temperature, in particular:

if the person was lying on an ear
if the person had ears covered
if the person was exposed to very hot or very cold temperatures or
if the person has recently swim or bathe.

In these cases, these external factors must be removed and wait 30 minutes before measuring the temperature.
If ear drops or other medications have been infused into the ear canal, use the other ear for temperature measurement.
For accurate measurement, the ear must be free from obstruction or excess kerosene.
Ear thermometers should not be used if the person has an external ear infection (otitis external) as they may cause pain.
Never measure the temperature in an ear that contains blood or secretions.

Thanks to its innovative technology, the Thermometer Braun Thermometer is one of the most accurate and reliable ear thermometers on the market.


Frontal temperature measurement is a delicate method. The front thermometers measure the infrared energy emitted from the skin above the eyebrow area and the surrounding tissues. This energy is collected through the lens and converted to a temperature value.

Various types of front thermometers are available on the market. To ensure accurate measurements it is important to measure the temperature exactly as indicated in the instruction manual.

Measuring body temperature with the Braun Thermometer No frontal touch is simple:

– Before performing a measurement, clean the forehead and move the hair.
In touch mode, position the thermometer on the forehead between the eyebrows or in the no touch mode, keeping it 5 cm away from the front; the proximity sensor and the orientation light will guide you in the correct positioning. For patients who measure the temperature alone, it is recommended to use the touch option in contact with the no-touch (distance) option.
Perform the measurement.
– The color code fever indicator helps interpret the measured value.

NOTE: The patient must be 30 minutes in a closed environment before performing the measurement. The patient and the thermometer must be at the same room temperature for at least 10 minutes.


This is a safe and direct method of measuring fever for children of all ages.

Here’s how to do it:

– Make sure there are no clothes between the thermometer and the baby’s skin.
– Introduce the tip of the thermometer under the armpit and hold it firmly, simultaneously lowering the baby’s arm and tightening it against your chest for a long time to allow for reading the temperature.



Oral temperature measurement is generally recommended for children who are already able to easily hold the thermometer in the mouth.

Here’s how to do it:

– Make sure the baby has not been drinking hot or cold drinks for the last 30 minutes and that it is quiet during the entire measurement.
– Gently place the tip of the thermometer under the tongue, sideways and towards the back of the mouth.
– Explain to the baby to hold the thermometer firmly with the lips and hands. If you use a digital thermometer that is more resistant than glass, the baby can bite the thermometer to hold it. The first times you probably will have to help it in the operation.
The tip of the thermometer should not be exposed to airflow during breathing because evaporation cools the sensor. – So let’s breathe the baby with the nose.



Rectal measurement is not difficult and does not make the child or parents uncomfortable. Some thermometers are specifically designed for rectal measurement and make it quick and easy.

Here’s how to do it:

– Sit the baby on your belly or back on a comfortable, stable and flat surface, eg, on your knees, on the changing table, on the couch or on the ground.
– If your baby is lying on your back, hold your legs up, as if you wanted to change your diaper. If it is to belly down, place it so that the buttocks are slightly raised by folding the knees under your body or making your legs lick on the knees.
– Spread a small amount of lubricating gel on the thermometer bulb.
– Gently insert the thermometer tip into the rectangle (anus) by penetrating all the metal tip (about one centimeter).
