For normal functioning, a person must have a body temperature of 36.6 degrees Celsius. Under such conditions, the body develops fully, and the person feels comfortable. Therefore, it is extremely important to constantly monitor the temperature of your body.

At the moment, there are a large number of special devices - thermometers. They are specifically designed to measure body temperature in an animal or human. But it is one thing to measure the temperature in an adult, and quite another in children. After all, they constantly strive to overturn something, which entails inaccuracy of indicators or damage to the device. For such cases, there is a special infrared thermometer.

Infrared thermometer - principle of operation

An infrared thermometer is a device that allows you to measure the temperature of an object without contact with it. The principle of operation of this device is quite simple: since the human body constantly emits thermal energy, the device is calibrated to its standard temperature (that is, the temperature 36.6 on the device is considered ideal and equal to zero). The laser beam that comes out of the device captures any changes in this indicator, thereby allowing you to display the finished measurement results.

At its core, it is a non-contact thermometer that captures changes in body temperature using a laser beam and some laws of physics. Here you do not need to constantly monitor that the child does not spoil it. It is enough to point the laser point at a part of the body (most often it is the forehead), press the button, and then get the finished measurement results.

For most models of such devices to work, just insert the batteries. In more expensive models, it is possible to charge from the network.

Accuracy of measurements

Each device has its own errors. Infrared thermometers are no exception.

Here, this value primarily depends on several factors:

  • ambient temperature
  • human position
  • instrument quality
  • battery level, etc.

In the aggregate of these factors, the error of the thermometer does not exceed 0.4 degrees Celsius. Of course, most contact devices, this figure is much smaller, but their operation process may not entirely meet the needs of the person.

To reduce the error, it is enough only to follow the rules of measurement, as well as use a high-quality device. In other cases, this can lead to poor quality measurements of body temperature.

Types of infrared thermometers

In pharmacies and online stores you can meet with a huge variety of types of such devices. At first glance, they differ only in their color and shape. But in fact, an infrared thermometer is produced in several forms.

These devices differ in the type of measurement - non-contact, ear and frontal. As you can guess from the names of these types, they make measurements in their own fields.

Need to know! Depending on the type of appliance. Measurements should only be made in the area in which the manufacturer recommends. This is due to the fact that most areas of the human body emit a different amount of heat and the device is calibrated specifically for its own.

In order to better understand their differences, you need to consider each of the species in more detail.

These devices differ from others in that they must be placed directly in the ear of a person to measure. They are not completely contactless, since some contact with the human body is still present. But the principle of the device is still based on infrared measurement.

The main disadvantage is its injury hazard when measured in children. If the measurement is, for example, in a newborn girl, then with careless handling, you can easily injure her auditory opening.

This type of instrument measures body temperature when pointing to a person’s forehead. This is a fairly safe device that does not need to lean against the human body.

Such thermometers are distinguished by their wide functionality, ease of operation, as well as their compactness.

Contactless

These devices are really the best and most reliable. They can be used in any conditions and measure absolutely any part of the body. It is enough to point at the site, and after a second the result will be displayed.

It can be used not only for people, but also for other objects. It is only necessary to calibrate correctly.

How to choose a reliable infrared thermometer

The most important condition for the success of the thermometer is its quality. To do this, you must still in the store decide on the choice of a reliable device.

To choose a reliable infrared thermometer, you need to follow a few rules:

  1. You need to purchase goods only in trusted stores. This is the most important rule, compliance with which will save not only money, but also time.

Often, such devices can be found on the counter of a pharmacy or in an electrical appliance store.

  1. When choosing, it is very important to look at the quality of the device. If there are cracks, then it is better to avoid such a purchase.
  2. As for the type of thermometer, here you should focus more on your own preferences. And most importantly - do not save! Most cheap products give a very large error, or even refuse to work at all.
  3. It is also necessary to pay special attention to the type of food. The best option are those that have a built-in battery. This is due to the fact that they give out the greatest voltage, which qualitatively affects the readings.
  4. Before buying, be sure to consult about the features of the device. This will not overpay for extra features.

If you follow these rules, you can purchase a really high-quality electronic thermometer. But if you neglect them, you can buy a dummy by spending your money.
