The invention discloses a thioether type gas detection device and method. The thioether type gas detection device comprises a gas cabin, a detection module, multiple sensors and a calibration module.The method comprises the following steps: calibrating the multiple sensors to obtain the calibration curve of thioether gases on a thioether sensor; obtaining response recovery curves of the thioethersensor, an ammonia sensor, a hydrogen sulfide sensor and a thiol sensor on the thioether gases; obtaining a respective response recovery expression of each sensor on the thioether gases according tothe response recovery curve, further obtaining a formula for judging whether sample gas is the thioether gas, and outputting the concentration value of the thioether gas in the sample gas according tothe calibration curve when the sample gas is judged to be the thioether gas. According to the thioether type gas detection device and method disclosed by the invention, due to use of the multiple groups of sensors, the cross interference problem of other gases on the thioether gases can be effectively solved, the thioether gases are accurately and qualitatively identified, and the concentration of the thioether gases is quantitatively calculated.
