ABSTRACT:
A device for the measurement of oil mists in a test gas comprises a glass tube which has ends which are openable such as by breaking off to permit a test gas to be directed therethrough. The glass tube contains in order in the direction of flow: a breakable ampoule filled with sulfuric acid, a particulate air filter, a distributor layer of quartz glass grit, and an indicator layer of deactivated silica gel. To effect a testing of a test gas it is directed through the glass tube after the tube ends have been broken off. Any oil mist and gas will be engaged with the filter layer. Thereafter, the ampoule is broken and sulfuric acid flows to the filter where it reacts with the mist and causes a defined color reading. In comparison with a color standard shows the oil concentration of the test gas.
