Title:
ガス濃度測定装置、及びその製造方法
Document Type and Number:
Japanese Patent JP6908192
Kind Code:
B2
Abstract:
A gas sensor, an oxygen concentration measuring unit, and a computation unit are included. The gas sensor measures a concentration CNOX of specific gas contained in measured gas. The oxygen concentration measuring unit measures a concentration CO2 of 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 CNOX of the specific gas by using the concentration CO2 of oxygen measured by using the oxygen concentration measurement unit and the sensor current.
