Nickel/Cadmium Aircraft Batteries: Multichannel Gassing-Rate Meter

Abstract

The instrument described is used to assess the state of health of separators in nickel/cadmium aircraft batteries and thus to permit removal from service of those cells which may be expected to fail catastrophically in the near future. Twenty channels are provided to permit simultaneous observation of all cells in a complete battery. Each channel measures the rate of emission of gas from one cell during overcharge by means of the pressure build up in a chamber from which the gas escapes via a suitable orifice. Construction, calibration and cleaning are discussed.
