The thermometer detects body temperature by measuring the infrared energy being emitted by the skin on the forehead. Teachers and professionals offering services such as osteopathy are using them to read the body temperature of adults and children to detect fevers before they are admitted to the premises.
Otherwise known as infrared (IR) thermometers, pyrometers, laser thermometers, non-contact thermometers, or temperature guns, these devices are very popular at the moment because they can be used at a distance. However, given their unreliability are the risks of damage to the eyes and pineal gland really worth it? In theory they measure temperature from a distance to reduce the transmission of any infection. No-contact forehead thermometers measure the temperature of the body based on the level of thermal radiation being emitted by the skin.
