Under the new coronavirus epidemic, the demand for infrared temperature measurement equipment has increased explosively
After the “extremely long vacation”, senior high school students from all provinces and cities across the country started school one after another.
At the entrance of the school and downstairs of the bedroom, a "new gadget" appeared: a camera and a display. When a person walks in front of the camera, it will be photographed on the display screen, and temperature data will appear on the head, which is convenient for the school to screen out those with abnormal temperature in time.
This is the infrared thermography temperature measurement equipment.
At present, this type of equipment is not only widely used in schools, but also used in shopping malls, stations, hospitals, communities, etc., to efficiently monitor the temperature of visitors.
How does infrared temperature measurement equipment realize non-contact temperature measurement?
As the name implies, infrared temperature measurement is to measure the temperature by absorbing infrared radiation emitted by the measured object. Specifically, objects with a temperature above absolute zero will emit electromagnetic radiation, and the radiation contains infrared radiation used for temperature measurement. The infrared camera can focus infrared radiation on the detector, and the detector generates an electrical signal proportional to the radiation. After the signal is amplified, it is converted into an output signal proportional to the temperature of the object by receiving continuous digital signal processing. Finally, the temperature measurement value is displayed on the display.
In practical applications, the concentration of people in the place will also affect the indoor temperature, resulting in false alarms by infrared thermometers. Therefore, many companies use blackbody to establish an accurate correspondence between grayscale and temperature, and perform temperature correction to reduce the error to ± 0.3 ° C.
Demand for domestic and foreign markets has increased significantly
Infrared temperature measurement equipment is a hot sale recently. According to the guidelines of the Ministry of Industry and Information Technology in February 2020, the demand for infrared thermometers around the country is about 20,000, and the demand for handheld thermometers exceeds 300,000. According to the analysis of Western Securities, if the number of domestic transportation hubs, office buildings, and communities is calculated, the overall demand for infrared temperature measurement equipment is close to 350,000 units. Under an optimistic scenario, the market space will reach 13 billion yuan, and the core suppliers ’operating income Or it will have 2-4 times the elasticity.
At the same time, overseas market demand also began to erupt, and demand in Southeast Asia, the Middle East, and Europe all increased significantly.
Security companies actively deploy capacity
The demand for infrared thermometers, infrared cameras and other instruments is increasing substantially, and security companies have also begun to actively allocate production capacity and develop products.
At present, our company is rapidly increasing the production capacity of thermal imaging sensors and temperature measurement equipment in order to meet the rapidly growing infrared temperature measurement needs.
