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..
How do I know if my infrared thermometer is accurate?
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.
What thermometer do hospitals use?
Hospital thermometers such as TRITEMP™ use sophisticated TAP&TAKE technology, meaning that the healthcare professional simply aims the device at the patient’s forehead, and receives an accurate core body temperature reading in seconds.
What temperature is a fever forehead?
The following thermometer readings generally indicate a fever: Rectal, ear or temporal artery temperature of 100.4 (38 C) or higher. Oral temperature of 100 F (37.8 C) or higher. Armpit temperature of 99 F (37.2 C) or higher.
Where is the best place to take your temperature with an infrared thermometer?
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.
Is 99.6 a fever for Covid?
For COVID-19, a fever is considered 100.0 degrees Fahrenheit or above for most people, and 99.6 degrees Fahrenheit and above for anyone 65 years and older or people who are immunosuppressed.
Are No Touch thermometers accurate?
Research has shown that, when used correctly, infrared or no-contact thermometers are just as accurate as oral or rectal thermometers. No-contact thermometers are popular among pediatricians, as kids often squirm around when trying to get a temperature read, but it also holds true in mass temperature screenings.
What temperature is a fever with infrared thermometer?
In conclusion, our study shows that commercially available, handheld infrared thermometers require individual validation. Forehead temperature in excess of 35.6°C (96.1°F) is suggestive of fever.
Why is neck temperature higher than forehead? The temperature is measured on the lateral side of neck, which lies closer to large arteries (carotid artery) than do the temporal arteries of the forehead region. Thus, neck IFR measures closely reflect axillary temperatures.
Where should I place my infrared thermometer?
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.
How accurate are forehead scan thermometers?
A forehead (temporal) scanner is usually 0.3°C (0.5°F) to 0.6°C (1°F) lower than an oral temperature.

Which forehead thermometer is the most accurate?
The Braun Digital No-Touch Forehead Thermometer was by far the best we tested. This thermometer guides you through the entire temperature-taking process with directions conveniently printed right on the front of the thermometer.
Which thermometer is used now in times of Covid? No-touch or non-contact infrared thermometers measure temperature through the forehead from a close distance in seconds. They may be used on newborns and older people. They’re easy to use and may reduce the risk of spreading disease by allowing more physical distancing.
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.
What is considered fever with infrared thermometer?
In conclusion, our study shows that commercially available, handheld infrared thermometers require individual validation. Forehead temperature in excess of 35.6°C (96.1°F) is suggestive of fever.
How accurate is a no touch thermometer?
The sensitivity and specificity for the non-contact thermometer is 97%. The negative predictive value is 99%, which is especially important to rule out fever and avoid unnecessary laboratory work-up.
What is the correct 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).
How accurate is forehead thermometer?
A forehead (temporal) scanner is usually 0.3°C (0.5°F) to 0.6°C (1°F) lower than an oral temperature.
