Method and apparatus for measuring the concentration of a gas

摘要

A method and apparatus using thermomechanical means for signalling the concentration of a reactive gas is disclosed. The thermomechanical means uses movement of a mechanical member to produce a signal corresponding to the concentration of the reactive gas in a gas stream. The method and apparatus may include means for converting a specific gas in a gas stream to a reactive gas. The apparatus may then provide an analog readout of the concentration of the specific gas.
