| titleOfInvention | Sulfur oxide detector |
| abstract | A sulfur oxide detector capable of improving the detection accuracy of SOx concentration in exhaust gas is provided. SOLUTION: A sulfur oxide detector 1 includes an element unit 10, a voltage application unit 61 that applies an interelectrode voltage to an electrochemical cell 51, a current detection unit 62 that detects an interelectrode current, and an interelectrode voltage. And a control unit 80 that controls and acquires an interelectrode current. After applying the first voltage between the electrodes for a predetermined time or longer, the control unit lowers the voltage between the electrodes from the first voltage to the second voltage while the water concentration in the gas to be measured is stable. When temporary step-down control is performed to increase the voltage to one voltage, and the difference between the inter-electrode current detected at the start of the temporary step-down control and the inter-electrode current detected at the completion of the temporary step-down control is small. It is determined that the sulfur oxide concentration in the measured gas is higher than The first voltage is a voltage equal to or higher than the decomposition start voltage of water and sulfur oxide, and the second voltage is a voltage capable of desorbing the decomposition product of sulfur oxide adsorbed on the first electrode.
