Abstract

A portable, remote controlled air sampler for measuring the solid, liquid, and gaseous emissions from sources such as a fossil fuel power plant, or ambient air. The sampler comprises a pump operated suction head movably mounted on a guide means for sucking a sample of air through a selected portion of an air filter strip, a motor operated translating means for translating the suction head along the guide means, and a radio operated, remote control system for selectively actuating the translating means and suction head. The preferred embodiment of the sampler is sufficiently lightweight to be suspended from a buoyant balloon six feet in diameter or less, or having a gas capacity of 115 cubic feet or less.
