The accuracy of an infrared thermometer can be checked using a comparator at any stable temperature. However, to reduce the possibility of a difference in temperature between the inside surface and the base test hole, it is more accurate at 22°C, ambient room temperature..
How reliable are infrared thermometers?
But studies now show that an infrared thermometer is just as accurate for taking a newborn’s temperature. Over a seven-day study of newborns, there was not a notable difference between infrared and axillary temperature readings. The accuracy of temperature readings varies by the type of thermometer you use.

What is a normal forehead temperature with an infrared thermometer?
Normal forehead skin temperature can vary several degrees depending on your environment (indoors or out), exercise, perspiration, direct heat or air conditioning, etc. It would be normal to read an actual forehead skin surface temperature between 91F and 94F if using a general-purpose infrared thermometer.
Are forehead thermometers accurate for adults?
How accurate are they? For general use at home, forehead thermometers will give an idea of whether or not an individual has a fever. However, according to a 2020 study, forehead thermometers are less accurate than other methods of reading temperature, such as oral, rectal, or tympanic (ear) temperature readings.
What time of day is body temperature highest?
Body temperature varies throughout the day and is lowest in the morning and highest in the afternoon. Your body has a complex thermoregulation mechanism to help keep its temperature within the normal ranges.
What is normal skin temperature?
Human skin temperature
The normal temperature of skin is about 33 °C or 91 °F. The flow of energy to and from the skin determines our sense of hot and cold. Heat flows from higher to lower temperature, so the human skin will not drop below that of surrounding air, regardless of wind.
What is the permissible temperature for COVID-19? The hospital operator decided to deny access for the clinical personal if the body temperature was above 37.4 °C. Beside this, information about the need of social distancing, hygiene standards and the use of the personal protective equipment was provided.
What is a normal forehead temperature?
While typically 98.6°F (37.0°C) is considered a “normal” temperature, some studies have shown that “normal” body temperature can be within a wide range, from 97°F (36.1°C) to 99°F (37.2°C). Before NCITs are used, it is important to understand the benefits, limitations, and proper use of these thermometers.
Is 99.6 a fever forehead?
Most healthcare providers consider a fever to be 100.4°F (38°C) or higher. A person with a temperature of 99.6°F to 100.3°F has a low-grade fever. High fevers may bring on seizures or confusion in children.
Is 99.3 a fever taken on forehead?
An ear (tympanic) temperature is 0.3°C (0.5°F) to 0.6°C (1°F) higher than an oral temperature.

Traditional thermometers can be placed in the armpit, mouth, behind the ear, and rectum. However, for infrared thermometers, the best place to measure temperature for accurate results is the wrist as they are less exposed to the external environment.
Do you add 1 degree to forehead thermometer?
A temporal thermometer will read at about 0.5 to 1 degree lower than an oral thermometer, so you need to add 0.5 to 1 degree to get what your temperature would read orally. For example, if your forehead temperature read as 98.5°F, you could actually have a low-grade fever of 99.5°F or higher.
