第１項に記載の微量ガスの測定器。[Scope of claims for utility model registration] (1) Sensor chamber 12 housing sensor 10 therein
A syringe needle 16 is connected to the sensor chamber 12, and a gas sampling tube 32 is connected to the rear of the sensor chamber 12, and a spring 44 is provided to automatically retract the piston 36 in the gas sampling tube 32. When the piston 36 is advanced against the force of the spring 44, the locking means 50 is activated to lock the movement of the piston 36, and when the lock is released, the piston 36 automatically moves back under the action of the spring 44. A trace gas measuring instrument characterized in that a base member 70 is attached to the gas sampling tube 32, and a stroke limiting means 74 for the piston 36 is provided on the base member 70. (2) The stroke limiting means 74 is
Utility model registration claim 1, comprising a nut 76 attached to the rear end of the piston rod and a bolt 78 screwed to the nut 78, and the tip of the bolt 78 can be engaged with the piston rod. The trace gas measuring device described in section.
