Zusammenfassung:The invention discloses a humidity adjusting device and a humidity adjusting method for gas component concentration detection. The device comprises a to-be-detected gas main flow path and two branchesbranched from the to-be-detected gas main flow path, wherein the two branches are respectively a first branch and a second branch; an adjusting unit which is arranged on the first branch and/or the second branch and can adjust the gas pressure in the corresponding branch; a humidity exchange part, which is arranged between the first branch and the second branch and is made of a water molecule permeable material, wherein when the gas pressure in the first branch is different from the gas pressure in the second branch, water molecules in the branch can move between the first branch and the second branch through the humidity exchange part; and a concentration detection unit that is arranged at the rear end of the first branch and used for detecting the concentration of the gas subjected to humidity exchange in the f
