PURPOSE: An exhaust gas sampling probe device capable of correcting a direction is provided to suck exhaust gas at a constant speed by arranging a suction surface formed on a nozzle unit of a suction unit in an exhaust gas flowing direction by using a direction measuring member, thereby accurately collecting and measuring a sample. CONSTITUTION: An exhaust gas sampling probe device includes a suction unit (10), a casing (20), and a direction measuring member (30). The suction unit is inserted inside a chimney (1) via a measurement hole (1a) formed on the chimney for sucking exhaust gas dispersing inside the chimney and includes a nozzle unit (11) with a suction surface (11a) capable of sucking exhaust gas; and a suction pipe (12) in which the sucked exhaust gas is moved. The casing is joined to the outer side of the suction unit. The direction measuring member is formed on the outer side of the casing and includes a horizontality meter or a verticality meter for arranging the suction surface of the nozzle unit in an exhaust gas flowing direction so that the exhaust gas is sucked at a constant speed. |
