[0044] figure 1 It is a schematic diagram of the gas detection system 1 of 1st Embodiment.
[0045] Such as figure 1 As shown, the gas detection system 1 includes a gas sensor 2 , an arithmetic device 4 and a display device 5 .
[0046] Such as figure 1 As shown, the gas sensor 2 has: an air inlet 21; a first flow path 24, a second flow path 25, a third flow path 26 and a fourth flow path 27 as four flow paths; The fifth flow path 28 of one flow path into which the gases of the paths 24 to 27 flow.
[0047] The air intake port 21 is used to inhale a detection target gas 23 from the outside.
[0048] The gas inhaled from the air intake port 21 can be guided to at least one of the four flow paths 24 to 27 .
[0049] Each of the flow paths 24 to 27 can guide the detection target gas 23 to the multi-array sensor 6 arranged on the fifth flow path 28 .
[0050]The gas can be mechanically introduced into the flow paths 24 to 27 at a constant flow rate by a fan, a pump, etc. not...

[0159] In the first embodiment, an example was given in which the first flow path having the dehumidifying and deodorizing filter and the second flow path having the deodorizing filter were provided, and the correction coefficient for calibrating the output value of the gas sensor 2 was obtained. , but not limited to this. A configuration may be adopted in which the correction coefficient is obtained by using at least two kinds of standard gases having different humidity without providing a dehumidification and deodorization filter and a deodorization filter. Next, use Figure 9 Be explained. In the following description, the same reference numerals are assigned to the same components as those described above, and descriptions thereof will be omitted.
[0160] Figure 9 It is a schematic diagram of the gas detection system 101 of the second embodiment.
[0161] Such as Figure 9 As shown, the gas detection system 101 includes a gas sensor 102 , a computing device 4 and a ...
