Abstract
An ion balance monitor for simultaneous monitoring of the positive and negative ion production rates, and therefore ion concentration, by measurement of currents resulting from the presence of airborne ions as created for example by an air (gas) ionizer. Additionally it examines the ion balance by comparing the aforementioned currents. Information acquired in this way can be used in real time monitoring of the ionizer. Ion balance and production rate of ions of both polarities can be recorded by the ion monitor, regardless of the type of the ionizer. The ion monitor can provide a feedback signal needed to keep an ionizer system in balance.
