Abstract
A device consisting of a monolithic block of material that is used as a housing of an apparatus for determining the density, or changes in density, of small particles, that contains an elongated chamber formed within the block that serves as a cloud chamber, and a trough formed in said block and defining a humidification chamber. The block includes passageways that connect the cloud chamber to the humidification chamber and inlet and exhaust passageways, as well as providing mountings for various valves, such as a humidity valve, by-pass valve, and vacuum valve used in the apparatus.
