PROBLEM TO BE SOLVED: To provide a gas sampling device capable of sampling an exhaust gas at a plurality of positions in an easier manner than ever before.SOLUTION: A gas sampling device 2 includes: an introduction pipe 20 for introducing an exhaust gas into a gas analyzer installed in an exhaust gas flow channel; valves 3, 4 provided to the introduction pipe; and a plurality of sampling pipes including sampling parts which open to the exhaust gas flow channel at positions different from each other in the exhaust gas flow channel. The plurality of sampling pipes introduce the exhaust gas sampled at the sampling parts into the valves. The valves control the flow of the exhaust gas from each of the plurality of sampling pipes to the introduction pipe.SELECTED DRAWING: Figure 1 |
