PATENT-ANSPRÜCHE : l. Luft-und Gasprüfer, bei welchem die Beimischung eines bestimmten Gases durch Farbänderung eines mit einer Reagensflüssigkeit getränkten Körpers festgestellt wird und die Flüssigkeit tropfenweise einem Behälter entnommen wird, dadurch gekennzeichnet, dass das Vorratsgefäss eine sich nach unten zu erweiternde Form erhält, die in ihrem unteren Teil sich wieder verjüngt oder sonst nach unten zurücktritt, zu dem Zwecke, den nach unten hängenden Prüfungsfaden durch Aufliegen auf der hervorspringenden schrägen Flasche in seiner Lage zu sichern. PATENT CLAIMS: l. Air and gas tester, in which the admixture of a certain gas is determined by a change in color of a body soaked with a reagent liquid and the liquid is taken drop by drop from a container, characterized in that the storage vessel is given a shape that widens downwards, the lower one Part tapers again or otherwise recedes downwards, for the purpose of securing the test thread hanging down in its position by resting on the protruding inclined bottle. 2. Luft-und Gasprüfer nach Anspruch l, dadurch gekennzeichnet, dass an Stelle der schrägen Wandung eine an der letzteren angebrachte schräge Verdacirmg oder eine lineare schräge Bahn, an welcher sich der Prüfungsfaden anlegt, vorgesehen ist. 2. Air and gas tester according to claim l, characterized in that instead of the inclined wall an inclined Verdacirmg attached to the latter or a linear inclined path on which the test thread rests is provided. 3. Luit-und Gasprüfer, bei welchem die Beimischung eines bestimmten Gases durch Farbänderung eines mit einer Reagensflüssigkeit getränkten Körpers festgestellt wird, dadurch gekennzeichnet, dass das zum Lufteinlass und zur Führung des Prüfungsfadens dienende Rohr eine Erweiterung besitzt, zum Zwecke, die Flüssigkeitsmenge, welche der Ausdehnung des Luftkissens oberhalb des Reagensflüssigkeitsspiegels durch äussere Wärmeeinflüsse entspricht, nach Möglichkeit aufzunehmen. 3. Luit and gas tester, in which the admixture of a certain gas is determined by a change in color of a body soaked with a reagent liquid, characterized in that the tube serving for air inlet and for guiding the test thread has an extension for the purpose of determining the amount of liquid which corresponds to the expansion of the air cushion above the reagent liquid level due to external heat influences.
