Claims

[Scope of Claim for Utility Model Registration] (1) A gas detection tube is attached to a gas sampling device, and the gas sampling device aerates the condensed sample gas into the gas detection tube, and the sample gas is extracted from the colored layer of the gas detection tube. An attachment for a portable gas detector for determining concentration, the attachment body having an engaging portion fixed to the gas sampling device at its base end extending from the distal end of the gas detection tube, and An attachment for preventing water droplets for a portable gas detector, characterized in that it has a shape that covers at least a part of the periphery of the tip of the gas detection tube. (2) In paragraph 1 of the claims for utility model registration,
The portable gas detection device is characterized in that the attachment body is comprised of an outer cylinder whose base end is engaged with the outer periphery of the gas sampling device, and an inner cylinder that is removably provided inside the outer cylinder. Attachment for preventing water droplets on containers. (3) In paragraph 2 of the claims for utility model registration,
Either one of recesses or protrusions is provided on the inner surface of the outer cylinder at regular intervals in the axial direction, and the other of the recesses or the protrusions is provided on the outer surface of the inner cylinder at regular intervals in the axial direction. Attachment for preventing water droplets in a portable gas detector, characterized by: (4) Scope of claims for utility model registration, paragraph 2 or 3
1. An attachment for preventing water droplets for a portable gas detector, characterized in that the tip of the inner cylinder is formed obliquely with respect to the axis. (5) Scope of claims for utility model registration, paragraphs 1 to 4
2. The attachment for preventing water droplets in a portable gas detector according to any one of the above items, wherein the attachment body is made of a transparent material.
