Abstract
A gas detection system includes a sensor unit that outputs a voltage corresponding to a concentration of a specific gas, a first chamber capable of storing a supplied sample gas, a second chamber located between the first chamber and the sensor unit, and a flow path connectable to an inlet of the second chamber. The second chamber has a smaller area than the first chamber in a cross section perpendicular to a gas flow direction in the first chamber. The sample gas is supplied from the first chamber to the second chamber, and then a purge gas is supplied from the flow path to the second chamber to supply the sample gas to the sensor unit.
