Abstract
A gas sensor 1 has a catheter 3 to which a gas sensor body 4 and a signal guide member 5 for guiding a detection signal of the gas sensor body 4 are attached. The other end of the signal guide member 5 is connected to a connector 6. The gas sensor 1 is airtightly received in the reception body in the state where a connection terminal of the connector 6 is exposed to the outside. The reception body 2 is filled with a mixed gas containing a gas to be measured by a predetermined concentration. At the time of calibration, the connection terminal of the connector 6 is connected to a measurement amplifier while the reception body 2 is not opened and calibration is performed, and at the time of measurement, the reception body 2 is opened and the gas sensor 1 is taken out to perform ordinary measurement.
