Is the digital forehead thermometer accurate?
There are several products on the market that test the body's temperature, including thermometers and temperature guns. When a patient goes to the hospital to check the temperature, the doctor usually measures the patient with a thermometer. In addition, many families have thermometers so that when someone in the family has a fever, they can measure it in time. So, is the digital forehead thermometer accurate?
Is the digital forehead thermometer accurate for measuring the forehead?
Digital forehead thermometers are generally quite accurate in measuring forehead. However, the forehead is easily affected by the external environment, resulting in a certain error in the forehead temperature.
It should be noted that, to measure the temperature of the forehead with a digital forehead thermometer, the hair must be lifted, and if there is sweat, be sure to wipe off the sweat. Then, after measuring 3-5cm from the middle of the forehead, press the start button, and after one second, the measured temperature appears on the display. Then this temperature is the forehead temperature. Hair on the forehead or sweat on the forehead, or wearing a hat or scarf may affect the measurement results of the digital forehead thermometer. In addition, under normal circumstances, people usually use mercury thermometers to measure the temperature of the armpits, which is also relatively accurate.
It should be noted that the digital forehead thermometer only detects the high and low temperature of the body surface, and cannot reflect the true temperature inside the body. Therefore, the digital forehead thermometer is only a simple screening tool. The body temperature measured by the digital forehead thermometer cannot be used as a standard to measure whether we have or are not diseased.
The most accurate part of the digital forehead thermometer measurement is the center of the forehead of the patient and above the center of the eyebrow. Aim the infrared detector at this part and keep it vertical. Be careful not to cover it with hair. If there is sweat, it must be wiped dry first. The distance between the probe and the forehead is about 3~5cm, and the temperature reading can be displayed after a few seconds.
