The novel coronavirus, which has spread across China and beyond now, urges us to be vigilant. The growing threat remains chilling as people infected with the virus will suffer in the respiratory tract or die in the severe. Therefore, it is necessary to improve awareness of self-protection. Not only do we insist on disinfection and cleaning every day, but we also strengthen the prevention in our residential area and workplace.
The obvious symptom of a patient infected COVID-19 is fever. We have to keep fully alert when someone’s temperature is found higher than 37.2 ℃. For places with a massive flow of population, such as residential areas and work areas, an infrared thermometer is necessary to be used to identify potentially infected peopleeffectively.
The infrared thermometer can convert the infrared ray emitted by the object to the electrical signal. The infrared ray from the human body has radiant energy, of which the size is related to the temperature of the object itself. We can tell the temperature of the object when infrared thermal imagers transform that energy into an electrical signal according to the relevant principles.
All objects above absolute 0℃ will radiate infrared rays by themselves. The function of an infrared thermometer is to collect the infrared rays emitted by objects and display the converted temperature on the screen. The infrared thermometer will not emit any harmful radiation at all, so it is harmless to the human body.
In places like communities, companies, and stations where people go in and out frequently, the probability that people get infected is high. It is suggested by experts that using a hand-held infrared thermometer to check the temperature of everyone who entered these areas can find out the infected timely.
Moreover, the infrared thermometer can improve a lot the work efficiency of checking the potential infected. First of all, it can sense the body temperature without touching each other, which can avoid the risk of infection and ensure the safety of the workers.
Secondly, the temperature of bodily different parts can be measured by infrared thermometers, including the forehead, armpit, ear, etc. That can ensure the accuracy of temperature detection to the greatest extent.
Finally, a hand-held infrared thermal imager can set the temperature limit. When the temperature detected exceeds the limit, it will automatically send out an audible alarm to help managers accurately check the abnormal body temperature in the crowd.
During the period of large-scale spread of the virus, the manufacturers of infrared thermal imaging cameras play a vital role in the work of epidemic prevention. Dali is an example in this case. Specializing in the production of infrared thermal imaging cameras, Dali offers different kinds of infrared thermometers to every place in urgent need of related devices. It is even at the door of a small convenience store that you can see its TE-W200 is working, not to mention at the international airport.
The TE-W series infrared thermal imagers of Dali are hand-held, online and portable. The hand-held infrared thermal imager (TE-W200) is small in size and easy to carry. When testing, a tester needs to hold the instrument to measure the temperature of the tested person.
The portable and online imager (TE-W300 and TE-W400) can be fixed on a tripod and placed at the entrance of a public place with a massive flow of people. It can output the image to the display without the direct operation of personnel. The tested staff does not need to stay. As long as they walk in front of the imager, the infrared thermal imager can automatically capture the temperature of the human body. When the temperature exceeds the warning value, the instrument will give an alarm.
The infrared thermometers can avoid the main shortcomings of traditional thermometers, such as time-consuming and energy-consuming, and effectively help managers to do an excellent job in epidemic prevention.
