Infrared thermometers for adults and how to use them. Which thermometer is better to choose for a newborn baby: rating of children's thermometers for measuring temperature. Medical infrared thermometer - definition
An infrared thermometer is modern device, which will determine the body temperature in just a few seconds, without even touching it. Quite recently, non-contact thermometers appeared in Medtechnika Orthosalon stores and immediately became popular. After some time, buyers began to complain about inaccurate measurements.
“We bought an infrared thermometer to measure the temperature small child. It seemed to my husband that he was pointing incorrectly. Therefore, they began to test with mercury. It turned out that infrared actually overestimates the readings.”
- Oksana, buyer of the Medtechnika Orthosalon store
It is worth noting that most people use this device incorrectly, which is the main reason for inaccurate readings. In this article we will tell you how to measure temperature correctly .

Non-contact thermometer error
Manufacturers indicate in the instructions the permissible error of thermometers:
mercury - 0.1°C
electronic - 0.1-0.2°C
infrared - 0.3°C
Users note that the error of the infrared thermometer sometimes reaches 0.5°C. This is already significant, isn’t it? Experts say that a sick person's body temperature can change by +/- 1°C within minutes. Mercury models take these fluctuations into account and show the maximum value. Infrared detects the temperature in 1-3 seconds, at a specific moment. That is why it is not recommended to check infrared readings with mercury.
Why does an infrared thermometer lie?
Even if we assume that you measure your temperature correctly with a non-contact thermometer, there are several more reasons for its “lies”:
cleanliness of the sensor (it should be free of dust, scratches and stains);
the air conditioner or heater is turned on in the room;
the patient's forehead is wet;
presence of cosmetics or creams in the measurement area;
dead batteries (batteries).
If you have been using an infrared thermometer for several months and it suddenly begins to display incorrectly, we recommend that you have it checked by service center manufacturer. This way you will definitely be confident in the quality of the data.
How to use an infrared thermometer
For a non-contact thermometer to show correct result, follow some rules for its use:
Eliminate extraneous air flows - air conditioner, fan, heater.
Make sure that the patient has a clean forehead, without makeup or creams.
If the person is sweating, wipe their forehead with a tissue.
Wipe infrared sensor soft cloth to remove dust particles.
Ask the patient to sit up straight and not move or talk during the measurement.
Brief instructions on how to correctly measure temperature with an infrared thermometer:

Temperature measurement
What is calibration and why do it?
The thermometer is mandatory element home first aid kit. This item should always be in good condition, because the temperature can rise at any time; measuring it will help provide timely medical assistance.
Recently, many people have begun to use infrared thermometers instead of standard mercury devices. These devices are convenient; they take readings in a non-contact mode. But accurate information can be obtained provided that the device is calibrated.
Using the IR Device
Calibration of an infrared thermometer consists of establishing a relationship between data measuring instrument and the size of the measured (input) quantity. In simple words, calibration is understood as the process of adjusting the measurements of a device to the actual indicators of the surface being measured.
Calibration is required to obtain accurate readings. Typically, modern IR products are calibrated by the manufacturer in the laboratory using special devices, so there are rarely any discrepancies in measurements.
Example of calibration in numbers
In order to understand what this is, we can consider an example. A good example will measure water using a conventional and infrared thermometer:
- when measuring medical device the water temperature in the bathroom is 36.6 0 C;
- on the display of the IR device – 36.3 0 C;
- to get accurate indicators, add 0.3 0 C to the figure;
- this figure should be added for subsequent temperature measurements.
Features of use

Often, in order to determine whether the temperature has risen, we place our hand on our forehead. With an infrared thermometer, you can get a digital reading of what you feel in your palm. - Wipe off perspiration from your forehead if your forehead is damp, so that when measuring the temperature, sweat evaporation does not cool your forehead.
- Turn on the thermometer and wait until the starting indicator is established (for more details, see the instructions for the specific model).
- Place the thermometer on your left temple so that the surface of the thermometer is in full contact with your forehead.
- Press the button and, holding it pressed (unless otherwise indicated in the instructions for a particular model), swipe from the left temple to the right. Make sure that the measuring surface does not come off your forehead.
- Release the button and wait for the end of measurement signal.
- After the signal, the thermometer can be removed from the temple and the measurement results can be viewed.
- The entire measurement cycle, including preparing the thermometer, will take you a few seconds.
This measurement method can be considered the most accurate. In the ear, the temperature of the eardrum, protected from external temperature factors by the bend of the ear canal, is measured. It is because of this bend that most often they get a result that does not correspond to reality, because they take readings not from the eardrum, but from the curved ear canal. Also, the cause of inaccurate measurements may be sulfur plug. Although crying, anxiety, rapid breathing and the presence of sulfur masses do not affect the measurement result. 
At correct measurement The normal temperature is:
- armpit 36.3 - 36.9 0 C;
- on the forehead 36.3 - 36.9 0 C;
- in the mouth 36.8 - 37.3 0 C;
- rectal 37.3 - 37.7 0 C;
- in the ear 37.3 - 37.7 0 C.
