This kit is used for detecting the presence of arsine gas.

The cover of the case is marked with the following: "Gasnachweispapier A mit Zube-hör".

The container is a gray cardboard box with removable lid and measures 3.3 x 4.9 x 7.4 inches. A sheet of paper with the directions for use printed on its glued to the inside of the cover. The box is divided into four compartments by card-board partitions. The two large compartments contain 100 detector packets, and the two small compartments, 30 plastic holders. The white test papers are bound together in the form of a booklet mea-suring 0.1 x 0.8 x 2.3 inches; there are 10 test papers per booklet. Each booklet is sea-led in a small packet which consists of two pieces of gray paper measuring 1.5 x 3.1 in-ches and sealed together with glued at the perimeter. The inside of the packet is coated with a light brown waterproofing compound.

The holder is made of transparent plastic material and consists of a pocket, a faste-ner and a slide. The pocket is formed by two rectangular shaped pieces of plastic mate-rial and has the dimensions 1.3 x 1.9 inches. The sealing margin around the perimeter is 0.1 inches wide. Three hollow rivets aid in the fastening of the two faces of the pocket. One face of the pocket has a tongue extending from the open end 0.6 inches to serve as the point of attachment for the holder-fastener. The latter is a nipple shaped plastic loop made to fit over a button or similar item.

The holder has a shield-like hole in front and back which expose the three holes of the plastic slide which is inserted into the pocket along with a piece of the detector paper. The three holes in the slide are each about 0.3 inches in diameter and produce spots on the paper about the same diameter; arsine produces yellow to brown spots.
