Forehead thermometers are the devices which measure the forehead temperature by measuring the infrared energy emitted from the skin surface above the eyebrow area. The emitted energy is collected by the lens and converted into the temperature values.
They are also known as temporal thermometers as they read the temperature at the temporal artery that is present below the skin. These thermometers can accurately read a person’s temperature in less than 10 seconds.

b) Further, slide the thermometer slowly across the forehead and towards the top of the ear but just near the hairline. Contact with the skin should not be lost.
