How to choose a non-contact thermometer
The choice of a non-contact thermometer must be approached responsibly. Our expert — MD, ENT surgeon of the highest category Konstantin Dobretsov will tell you what you need to pay attention to when buying.
— A non-contact thermometer (pyrometer) is a medical product, so it must have a registration certificate (certificate) and instructions in Russian. Do not trust your health to non-certified devices, even if they are cheap. It is also worth paying attention to the main characteristics of the pyrometer:
Measurement range. It is necessary that the pyrometer covers the possible indicators of the temperature of the human body, from 30 to 45 degrees.
Measurement error. It is very important that the measurement error is not more than 0.2 degrees, otherwise the indicators will be unreliable.
Measurement speed. This indicator is very important for measuring body temperature in children and should not exceed a few seconds.
Measurement memory. It is very convenient when the thermometer remembers past data, which makes it possible to monitor changes in body temperature for several days.
Display illumination. This option allows you to take thermometry at night without turning on the light, which is very convenient when measuring temperature in children, the expert says.
Popular questions and answers
Konstantin Dobretsov, doctor of medical sciences, ENT surgeon of the highest category, answers the popular questions of our readers about where it is right to measure the temperature with a thermometer, why the device overestimates the temperature and others.
Where is the right place to measure the temperature with a non-contact thermometer?
- The device has a special sensor that captures infrared radiation from the human body without contact with the skin. To get the value on the display, you need to point the device at the wrist, forehead of a person or other part of the body where it will be necessary to measure the temperature. Most often, the device is calibrated to an average human body temperature of 36.5 degrees. The device at a distance immediately captures the high infrared radiation associated with the excess of the usual indicator. Therefore, it is necessary to point the pyrometer at the opening of body parts (forehead, wrist) so that the indicators correspond to the calibrated values.
Why does a non-contact thermometer overestimate the temperature?
— It is very important that the infrared thermometer has a certificate of quality. Only in this case you get a proven medical device that you can trust. The thermometer must be calibrated and show reliable readings. In addition, the device should have a small error (no more than 0.2 degrees). If the error is greater, then the data may differ from the actual temperature.
Why is it impossible to measure the temperature on the forehead with a non-contact thermometer?
- The distance from the device to the skin should be 3–5 cm. In this case, the heat beam will be focused on a special sensor lens, which converts the radiation into an electrical signal. Otherwise, if the focal length is smaller, the results may not be entirely reliable.
