Basic knowledge of infrared thermometer application
When an infectious disease with fever symptoms breaks out, the infrared thermometer is widely used in public places where people gather, such as hospital clinics, airports, subway stations, and entry-exit visa and quarantine stations. Infrared thermography and thermal imaging are two types of equipment used to measure body temperature. (Infrared Thermometer) Thermal Imaging Body Checker If many people use infrared thermometers, will it cause infection?
Researcher Feng Lu from the Chinese Center for Disease Control and Prevention replied at the exhibition: "According to the basic principle of infrared thermometers, human body temperature can be measured without touching the skin. When measuring accurately, both the accurate measurer and the accurately measured person wear protective masks. Therefore, the probability of infection is extremely low." When using an infrared thermometer, you should pay attention to your own safety when measuring the temperature. Objects, with an interval of about 1-5cm; only by accurately measuring the ambient temperature, the infrared thermometer can accurately measure the internal temperature Steam, dust, and dense smoke will stop the optical and electronic systems of the instrument and equipment, endangering accurate temperature measurement; if the infrared thermometer is suddenly exposed to the natural environment When the temperature difference is above 20°C, the accurate measurement results will be shifted instantly; do not aim the laser at the eyes immediately.
So, how should the infrared thermometer be used? Will the infrared thermometer be accurate as long as it accurately measures the temperature of the forehead?
The accurate measurement accuracy of the infrared thermometer is initially related to the accuracy level of the instrument itself and the quality of the instrument itself. Secondly, the calibration temperature of the testing instrument in the laboratory is different from that of the evaluation temperature, which may easily cause data errors; at present, infrared thermometers measure the forehead, palm, face and other positions of the person, and the accurate measurement results belong to the human body. The body surface temperature of the body surface temperature fluctuates due to the hazard of the activation state, so it does not necessarily mean the actual body temperature of the human body.
Please keep the user and the infrared thermometer at a stable room temperature for at least 30 minutes before application. However, during the epidemic prevention and control period, there is no guarantee to wait 30 minutes before taking the body temperature. After continuous inspection, the staff scientifically studied the small technology of accurate measurement with forehead thermometer. Please be exposed to the measuring person, covered by clothes and pants, and expose a part of the skin of the wrist that is not exposed to the gas, and take the correct measurement at a distance of 6-8 cm between the wrists. That way the correctly measured temperature is close to the actual temperature of the body.
