Publication number: 20240102957Abstract: In an electrochemical gas sensor (10), a first sensing element (21) is stored in a first storage portion (31). A moisture permeable film (24) is disposed in a first introduction inlet (31A) of the first storage portion (31). The moisture permeable film (24) substantially prevents a to-be-detected gas from permeating therethrough. A second sensing element (22) is disposed in a space into which water vapor and the to-be-detected gas contained in a target gas flow. In such a configuration, the electrochemical gas sensor (10) is capable of detecting a to-be-detected gas having a concentration of 0 or more and 1 ppm or less.Type: ApplicationFiled: March 8, 2022Publication date: March 28, 2024Inventors: Shinichiro KITO, Masayuki SEGAWA, Takahiro YOKOYAMA, Junya IMAIZUMI, Yuki MIZUTANI, Masahiro TANAKA, Yoshiko KUMAGAI
