PROBLEM TO BE SOLVED: To provide a gas detector capable of adjusting the gas flow rate for each of a plurality of sensors.SOLUTION: The gas detector X includes a plurality of sensor units 10-50 having sensors 12-52 for detecting the variation of an external environment. The sensor units 10-50 include pumps 15-55 for sucking atmosphere gas, respectively. Even when inconvenience is caused by excessive suction force depending on the type of the sensor, the gas detector performs gas detection with an appropriate flow rate corresponding to the characteristic of each sensor by adjusting the flow rate of the atmosphere gas by adjusting the suction force by the pump for a desired sensor. |
