Abstract: In general, an electrochemical sensor or a non-dispersive infrared spectroscopy (NDIR) method is used as a method of measuring NOx. However, this is an unsuitable measuring tool for measuring a very low concentration of NOx. This is the reason that a NDIR sensor for measuring the concentration of gas by using infrared absorbance has low absorption efficiency in NOx gas so that the same cannot measure a low concentrations of NOx. To solve the above problem, the present invention provides a NOx measuring device using a chemical color development method. The NOx measuring device comprises: an insulated outer cylinder; a heater for regulating the temperature inside the outer cylinder; a molybdenum catalyst formed by stacking 20 to 50 layers of molybdenum wire meshes inside the outer cylinder in which the heater is located; and a NO_2 to NO converter using a catalytic method for converting NO_2 into NO by removing moisture and dust from exhaust gas discharged from a chimney through the molybdenum catalyst. Therefore, the NOx measuring device can continuously measure nitrogen oxide included in the exhaust gas of the chimney to a low concentration, without overheating of the NOx measuring device.
