1.How the forehead infrared thermometer works
The infrared thermometer measures body temperature by absorbing the infrared radiation
energy reflected from the human body.
Any object will emit infrared light when it is above absolute zero (-273 ° C), and
the forehead infrared thermometer receives infrared light through the sensor to obtain
the sensing temperature data.
The forehead infrared thermometers measure temperature by absorbing energy, so they
don't cause harm to the human body when measuring body temperature.
2.How to use forehead thermometer correctly
When measuring body temperature, point the instrument in the center of the forehead
and keep it vertical to avoid obstruction of clothing or hair, distance 3cm-5cm.
Sweating in the forehead will dissipate a lot of heat, which will reduce the body
temperature of the forehead. When measuring, the head sweat should be dried in advance
to prevent measurement deviation.
It is more accurate to measure parts covered by clothing outdoor, such as the wrist or
It is recommended to measure about 3 times during the measurement, based on the
average body temperature value.
