After 10 seconds, the display device 140 displays a gas pressure value of 25 Pa, and the user can determine the air pressure value according to the air pressure value. The sealing performance of the sealing device is determined in a 10 second change condition, and it can be further determined whether the sealing device can be adapted to a certain working environment according to the sealing performance of the sealing device.
