ABSTRACT:
The invention disclosed is a device for monitoring the penetration of vapor from a challenge liquid occluded by a garment material, through the garment material, wherein pressure is applied against the garment material. The vapor which penetrates through the garment material is picked up by an inert carrier gas and detected to determine the protection afforded by the garment material against penetration by the challenge liquid/vapor.
