Abstract: A gas analysis device includes a light source configured to emit laser beam to a target gas, a reflection body which reflects the laser beam, a light reception device that receives the laser beam reflected by the reflection body, a container which contains the light source and the light reception device, and an alignment mechanism that includes an insertion member inserted from outside of the container to inside of the container to move, along a plane intersecting with the irradiation direction of the laser beam, at least any one of the light source and the light reception device.

Abstract: A measurement apparatus includes a sensor probe and a circuit housing. The sensor probe is insertable through an opening provided in a flow path wall of a flow path through which a fluid to be measured flows and is used in a predetermined orientation relative to the flow direction of the fluid to be measured. The circuit housing includes a display, disposed outside of the flow path, and connects to the sensor probe. The circuit housing is fixable at a plurality of rotation positions relative to the sensor probe about an axis along the insertion direction of the sensor probe. The measurement apparatus allows the display direction of the display to be selected regardless of the orientation of the sensor probe.
