What is forehead thermometer?
The temperature of human is also
measured through its forehead. It can be easily obtained with the help of infrared digital thermometers[1].
How does forehead thermometer work?
Forehead thermometers normally come as non-contact digital thermometers. These thermometers use digital infrared technology or IR technology. The probe of these thermometers is equipped with sensor[2] which measure human body temperature through infrared wave.The probe consist of lens to focus infrared energy. It basically detects energy emitted by the surface as result of infrared waves from thermometer and converts into heat. The intensity of heat is displaced in units such as Celsius or Fahrenheit.
Where to place forehead thermometer?
How does a infrared thermometer work depends up its use. When directed towards forehead, the body temperature of human is recorded through temporal artery temperature. Because fever temporal temperature provide accurate reading. There is significant space about 3 to 5 cm must be maintained to obtain accurate temperature reading.How accurate are infrared forehead thermometers?
The accuracy of instruments varies with the manufacture and is generally between 0.1 to 0.3 degree Fahrenheit.
