PURPOSE:To provide an oxygen analyzer which can correct output gas pressure highly accurately while exhibiting excellent measurement accuracy stably. CONSTITUTION:The oxygen analyzer comprises a sensor element 24 having at least one electrochemical cell comprising an oxygen ion conductive solid electrolyte and at least a pair of electrodes connected with a combustion exhaust gas duct 16 and outputting an electric signal corresponding to the concentration of oxygen in the exhaust gas, where a coupling port of pressure gauge 34 is made in a nipple 20 coupling the sensor element 24 and the duct 16 in order to measure the pressure within the nipple 20. |
