  • Patent number: 4114088
    Abstract: An ion counter for measuring the density of atmospheric ions has two basic sections, the electrometer, which is of a conventional type, and the collector. An improved collector is provided having two collector plates in electrical contact, mounted either side of a polarizing plate to form a double channel cell having two air passages. The polarizing plate and the collector plates are tightly secured to insulators so as accurately to maintain the spacing between the plates.
