The present invention relates to a gas measuring device for measuring an element or a state of gas flowing in an exhaust pipe. According to an embodiment of the present invention, the gas measuring device comprises a probe, a main inspection flow path, at least one sensor, a compression air flow path, and a bypass flow path. The probe has at least one suction hole and is inserted into the exhaust pipe. The main inspection flow path allows gas introduced through the probe to be moved. The sensor is installed on the main inspection flow path to sense gas. The compression air flow path receives compressed air from the outside, is joined with the main inspection flow path, then is connected to the exhaust pipe, and provides vacuum suction force to the main inspection flow path. The bypass flow path is branched from the compression air flow path before a point joined with the main inspection flow path to be connected to the main inspection flow path. The gas measuring device can effectively measure the element or the state of gas regardless of surrounding environment. |
