Abstract
A gas sensor, an oxygen concentration measuring unit, and a computation unit are included. The gas sensor measures a concentration Cof specific gas contained in measured gas. The oxygen concentration measuring unit measures a concentration Cof oxygen in the measured gas outside the gas sensor. The gas sensor has a measured gas chamber, a reference gas chamber, a diffusion resistance unit, a pump cell, and a sensor cell. The computation unit computes a concentration Cof the specific gas by using the concentration Cof oxygen measured by using the oxygen concentration measurement unit and the sensor current.
