Forehead Thermometer: The Best Models

Very often present in homes, the medical thermometer is an accessory used to measure body temperature in case of fever. Practical equipment that has evolved a lot in recent years. Indeed, with the evolution of technology and needs, the thermometer market has seen the arrival of different models including the contactless medical thermometer. Modern, practical, it can accurately measure the temperature of a target from a distance. A little gem of technology that we will show you in all its aspects and… make you adopt?

The forehead thermometer: how does it work?

It is above all a measuring device which generally makes it possible to take the temperature of a human body. In its mode of use, it has the particularity of not requiring contact with its target to take a measurement.

In fact, unlike the classic mercury thermometer, the infrared thermometer allows you to measure the temperature on the surface of an object without touching it. This is thanks to a lens, a sensor, and a computer that evaluates the temperature of the signal received on the basis of several algorithms. It is currently the most advanced thermometer model available on the market.

How does it work?

Although the most advanced form of thermometer there is, it is based on a relatively simple principle of operation.

In fact, the non-contact thermometer captures infrared radiation through its lens which amplifies the signal that will be received by the sensor and then the calculation unit in order to deduce the temperature therefrom. It should be remembered that anybody (inert or not) gives off infrared radiation, the power of which determines its temperature.

The tool is therefore content to measure the length of this wave and to deduce the temperature of the object proportionally using its calculation algorithm. It then displays the result on an LCD screen. In general, non-contact thermometers are programmed to sense wavelengths between 7 micrometers and 15 micrometers. In degrees Celsius, this equates to a range of -60 to 450.

The advantages of the non-contact forehead thermometer?

This device has many advantages, the most important of which is undoubtedly its ability to measure the temperature of a body from a distance. Thus, there is no need to wake your baby from sleep, take off his clothes, or make him feel the unpleasant sensation of a probe in his ears to take his temperature.

Another important advantage is that it is hygienic. Since it does not require contact with the target, there is, therefore, no risk of disease transmission. Which is a big plus compared to classic models.

Precision and speed are also two other advantages of the infrared medical thermometer. Indeed, it is much more precise than all the other thermometer models, giving measurements faithful to the degree. It, therefore, provides its measurements in a very short period of time (a few seconds).

Also to its advantage, its practicality. It usually allows you to take the temperature of any type of body, regardless of its position and characteristics.

How to choose the right forehead thermometer?

There are several aspects to consider when choosing a good infrared thermometer.

Precision and reliability

At the top of the list, we find the criteria of precision and reliability. Two elements that alone determine the relevance of the choice of using an infrared thermometer. They should not be neglected. It is therefore recommended to choose thermometer models equipped with several sensors, as they allow extremely precise and therefore reliable measurements to be made.

Practicality

It is always good to choose a medical thermometer that has many useful features. For example, make sure it has a built-in backlight function. So you can read the measurement result even in the dark. Also favor other practical features such as interpretation by color codes, memorization for the progressive monitoring of fever, or automatic shutdown to save energy. Anyway, taking this criterion into account is intrinsically linked to your needs and your budget.

The price

Another criterion of choice, that of the price. It differs from model to model and often indicates how fast the model is calculated. Thus, the shorter the calculation time and the delay in displaying the result, the more expensive the thermometer. The price also depends on the level of features that the device offers. Thus, the more complete it is on this point, the more expensive it will be. However, the costs of non-contact medical thermometers are generally affordable and there are some very functional ones that sell well on the internet.

How to use your non-contact thermometer?

It is very easy to use. To obtain a reliable result, it suffices to place its lens directly in front of the measured body. The latter must also be within easy reach of the device (ideally 5 cm). It is especially important to ensure that there are no obstacles between the body and the device, at the risk of falsifying the measurement. To get an accurate reading, the body being measured must completely fill the lens surface that represents the thermometer's field of view. Another precaution of use, always makes sure that the lens of the thermometer is clean as well as the surface of the body to be measured. This is to avoid any measurement error.

Our pick of the five best forehead thermometers

We have selected for you the top five best infrared medical thermometers. Features, pluses and minuses, here's a quick description of each.

The Braun NTF3000WE

Braun NTF3000WE is a multimode medical infrared thermometer. It makes it possible to take the temperature by or without contact with the forehead. Intended for all age groups, it has an ergonomic shape that makes it easy to handle and use. In terms of functionality, it is rather well endowed. It thus has a proximity sensor that tells you if the thermometer is placed at a good distance from the forehead (5 cm max) for optimal temperature measurement. The device also emits a yellow guiding light that clearly points to the body part you are targeting. However, it is not easy to apply to oneself. Another interesting feature is its three-color display mode. Depending on the degree of temperature measured, the backlight of the large LCD screen will be green (normal fever), yellow (mild fever) or red (high fever). This will allow you to more easily interpret the result. In addition, the tool has a powerful calculation unit allowing it to display the setting result in 2 seconds. It also has a silent mode that can come in handy when you want to take your baby's temperature while sleeping.

Terraillon Thermo Distance

The Thermo Distance is an infrared thermometer designed by Terraillon. It has a clean look and seduces as much by its simplicity as its ergonomic shape. It only has two main buttons and a backlit LCD screen for viewing results. Equipped with an infrared probe, it allows you to take the temperature of a body without physical contact at a distance of 0 to 5 cm. A beep even tells you if the thermometer is ideally positioned. In use, the Thermo distance measures the temperature of various types of elements (human body, bottle, ambient air, bath). A multi-use tool, therefore, whose measurement interpretation is facilitated by a color code. Each reflecting the degree of rising in the measured temperature. If it is rather simple in its operation, the Thermo Distance integrates the very particular functionality of memorization. It memorizes the last 9 temperatures measured, in order to facilitate monitoring of the condition over time in the event of treatment.

Baby Thermometer, SVMUU Digital Infrared 

It is one of the most popular models on this list. Although its design is not the most successful, it offers an interesting quality/price ratio. Affordable, the Svmuuest infrared thermometer is full of interesting options. It is multifunctional and notably offers three modes of use: body, surface, and animal. You can switch to each mode with a selector on the top side of the device. The choice of model will depend on the temperature range used and you can even choose the unit (degrees Celsius or degrees Fahrenheit) in which the measurement will be displayed. In the case of a body temperature measurement, the integrated fever alarm function will then indicate the degree of severity through its color code: green for normal, yellow for mild fever, and red for high fever.

The accuracy of the measurements is guaranteed by the adjustment selectors placed on the side face of the object, the possible margin of error being 0.2 ° C or 0.36 ° F. Its powerful calculation unit allows it to display the result in just half a second. In addition, it switches off automatically when not in use and has a memory system. The latter can record up to 99 measurements, allowing you to easily follow temperature changes over time.

Frontal ThermometerBb Infrared Thermometer

We could easily award him the prize for the most beautiful infrared thermometer on this list. Carefully finished and presented, the Go ecoThermometer Frontal Contactless combines the useful with the pleasant. Indeed, its practicality stands out in many aspects. This is particularly the case with its shape which makes it easier to handle, its multiple measurement modes (body, surface, food, air, etc.) or even its two measurement units (Celsius or Fahrenheit).

Intuitively, it is very easy to use and offers a high level of precision in its measurements with a margin of error of only 0.1 ° C. It also has a display in three colors, each corresponding to a certain degree of severity.

In addition, it is also equipped with the memorization function with the possibility of recording in memory up to 30 measurements. In the event of inactivity (after 15 s), it switches off automatically to save the energy of the 2 AAA batteries fitted to it.

 Conclusion

Innovative, all these infrared thermometers have specific features intrinsically linked to the use for which they are intended. It is therefore difficult to establish a hierarchy, as each offers interesting features.

However, there is a slight advantage to the Careva model, which in addition to being very beautiful and inexpensive, offers a full range of features. Equally functional, the Mvmuu is an infrared thermometer that just fishes at the level of its "coarse" look.

That said, all are very good quality thermometers, practical and for the most part guaranteed. It's up to you to decide which one is the best according to your needs as well as your budget!
