In addition, the gas inlet 201 is used to collect oxygen samples in the surrounding air to ensure accurate measurement of the oxygen concentration in the environment. The gas inlet 201 of sensor 2 passes out of casing 1 through the first opening 104 on casing 1, and the second sealing ring 108 ensures the sealing performance between the first opening 104 and the gas inlet 201, protecting the components inside casing 1.
