[0027] When the utility model is in use, each mounting seat 2 is connected in series (using a plastic connecting hose and an air pipe), that is, the gas is connected from the air inlet 221 of the first mounting seat 2, and then discharged from the air outlet 222, and the discharged gas is connected from the air inlet 221 of the second mounting seat 2, and so on, all the mounting seats 2 are connected in series; as shown in the drawings of the embodiment of the utility model, the mounting seats 2 are divided into two groups, each with eight, and the groups can be selectively connected, and the eight in the group are connected in series (it can also be selected according to the actual number, and it can also be used when the number is less than eight), so when in use, the sensor 4 is connected to each mounting seat 2, and then the gas of standard concentration is connected to realize the detection of the sensor 4.
