PURPOSE:To easily extract and collect the exhaust gas in the dry state and perform a correct analysis by inserting and fixing the inner end of a sampling tube penetrating a drive shaft into an exhaust tube, and sealing the outer end opening section of the sampling tube with a cap. CONSTITUTION:A screw member 9 is outwardly coupled and fixed on the outer periphery near the inner end of a sampling tube 8, a screw 10 on the end section outer periphery of the screw member 9 is screwed into the screw hole 11 of an exhaust tube 7, and the hexagonal head section 12 of the screw member 9 is rotated and fastened to maintain the airtight state. An O-ring 19 coupled with the ring groove 18 of a plug 16 is pressed to the face of the flange 20 of the sampling tube 8 to maintain the liquid-tight state. A cap 22 is screwed to a screw 21 on the outer periphery of the outer end opening section 8a of the sampling tube 8 to seal the opening section 8a. The cap 22 is removed to extract and collect the exhaust gas flowing in the exhaust tube 7, and the exhaust gas is sampled from the outer end opening section 8a of the sampling tube 8. |
