Abstract

A gas analyzer includes: a gas measuring portion which performs a measurement on a gas; a case which houses the gas measuring portion; a liquid separator which includes a reservoir for storing a liquid component separated from the gas; a holder portion which holds the liquid separator; and a rotation mechanism which mounts the holder portion to the case.

Claims

1. A gas analyzer comprising:

a gas measuring portion which performs a measurement on a gas;

a case which houses the gas measuring portion;

a liquid separator which includes a reservoir for storing a liquid component separated from the gas;

a holder portion which holds the liquid separator, and which is rotatable with respect to the case; and

a rotation mechanism which mounts the holder portion to the case, the rotation mechanism configured such that movement of the holder portion causes a gravitational force to rotate the holder portion along an axis so that the reservoir is positioned in a lowermost portion in the direction of the gravitational force in the liquid separator.

2. The gas analyzer according to claim 1, further comprising:

a locking unit which locks the holder portion in a case where the holder portion is rotated to a position where the reservoir is in the lowermost portion in the direction of the gravitational force in the liquid separator.

3. The gas analyzer according to claim 1, further comprising:

a sensor which detects an attitude of the holder portion with respect to the direction of the gravitational force.

4. The gas analyzer according to claim 3, further comprising:

an alarm unit which generates an alarm in a case where the attitude of the holder portion which is detected by the sensor is not in a predetermined attitude in which the reservoir is positioned in the lowermost portion in the direction of the gravitational force in the liquid separator.

5. The gas analyzer according to claim 3, further comprising:

a transmitting unit which transmits a detection signal in a case where the attitude of the holder portion which is detected by the sensor is not in a predetermined attitude in which the reservoir is positioned in the lowermost portion in the direction of the gravitational force in the liquid separator.
