The situation of the pneumonia epidemic caused by the new coronavirus is not optimistic, and temperature measurement has become a necessary means to prevent the large-scale epidemic of pneumonia. Human infrared thermometer has the characteristics of non-contact, high efficiency and convenient use, and is widely used in traffic travel passes, hospital outpatient clinics, residential quarters, government agencies and institutions and other fields.
Common human infrared thermometers can be divided into two categories: infrared thermal imaging rapid human body temperature screening instruments and infrared thermometers. Infrared thermal imaging rapid human body temperature screening instrument can perform large-scale detection in crowded public places, automatically track and warn high temperature areas, and cooperate with invisible light video to quickly find and track staff with high body temperature. When the infrared thermal imaging human body temperature rapid screener integrates technologies such as face recognition and mobile phone probes, it can also grasp other information of staff with high body temperature. Infrared thermometers can be divided into infrared ear thermometers and infrared forehead thermometers. The infrared thermometer is simple to operate, easy to use, and cost-effective, and can be used to quickly measure the temperature in the order of the staff. Basic principles and precise measurement methods Human body heat is released into the natural environment in the form of radiant heat. The human body infrared thermometer detects the radiant heat of the human body according to the built-in controller, and then completes the purpose of measuring body temperature.
Infrared thermal imaging rapid human body temperature screening instrument adopts infrared thermometer technology to perform non-contact rapid and accurate measurement of human body ambient temperature. It is an instrument that alarms when the measured temperature reaches or exceeds the preset alarm temperature value. An infrared ear thermometer is an instrument that uses infrared radiation between the ear canal and ear drum and a detector to exchange body temperature; it accurately measures the position of the body's ear drum. The ear hole must be cleared before accurate measurement, and the camera must be accurately measured in the deep ear hole. Equipped with sanitation earmuff application to prevent multiple infections. An infrared forehead thermometer is an instrument that accurately measures skin temperature by utilizing the infrared radiation exchange and appropriate emissivity adjustment between the skin and the detector. The precise measurement is the position of the body's forehead. Aim the temperature gun at the center of the forehead. If there is sweat, it should be wiped dry. 1-3cm from the forehead is recommended. The advantages of infrared thermometers: First, it does not touch the measured target, and it is not easy to cause additional sensations when measuring body temperature; second, it is fast, and the accurate measurement time is generally within 1 second, and it is generally not easy to exceed 2 seconds. Therefore, it is very suitable for the prevention and treatment of high fever diseases.
