Portable Medical Infrared Thermometer , Non Contact Forehead Thermometer
 
 
Introduction
 
The infrared thermometer used to measure the temperature of the human body is called the human infrared
thermometer. But it must be clarified that there is no special medical or industrial infrared thermometer, because
the manufacturing principles of infrared thermometers are the same. There are only high precision, high distance
coefficient ratio, high performance infrared thermometers and low precision, low distance coefficient ratio and low
performance infrared thermometers. As long as the emissivity of the infrared thermometer is set to 0.95 (the
emissivity of human skin is generally this value, even if there is a difference, the impact is only within 0.3
degrees), it is in line with the requirements of human body temperature measurement.
 
Temperature measurement principle
 
The principle of infrared thermometer's temperature measurement is to convert the radiant energy possessed by
infrared rays emitted by the measured object into electrical signals. The amount of infrared radiation energy is
related to the temperature of the object itself, and the temperature of the object can be determined according to
the size of the converted electrical signal. All objects above absolute zero will radiate infrared rays by
themselves. The function of the infrared thermometer is to collect the infrared rays emitted by the object. It will
not emit any harmful radiation at all, so it is completely harmless to the human body. Some people have
misunderstood that infrared thermometers emit radiation to the human body to produce readings. This concept is
wrong.
 
Features
 
The hand-held infrared imager is small in size and convenient to carry. During the test, a tester needs to hold the
instrument to measure the temperature of the person under test. The portable imager can be fixed on a tripod and
placed at the entrance of a public place with a large number of people. It can output images to the display without
the need for direct operation by personnel. The measured person does not need to stay, as long as he walks in front
of the imager, the infrared imager can automatically capture the temperature of the human body, and the instrument
will sound an alarm when the temperature exceeds the warning value.
