Abstract
PURPOSE:To obtain oxygen concentration signel that is free of change with time and drift and is stable by making the reference gas and a gas to be measured contact with the electrolyte that contains bicarbonate of alkali matals. CONSTITUTION:Two pieces of oxygen permeation films 31 and 35 are arranged in a vessel 2 and an electrolyte 5 is filled between the oxygen permeation films in the vessel 2. In this electrolyte electrodes 41 and 45 are arrangd inside of the oxygen permeation films. The electrolyte 5 is a solution of the bicarbonate of an alkali metal such as NaHCO3, KHCO3, etc. in an electrolyte of the hydroxide of an alkali metal such as LiOH, KOH or NaOH, so that the electrolyte 5 contains bicarbonate ion HCO3<->. In the electrolyte 5 thus produced dissolution of the carbon oxide gas in the air is suppressed with the result of reduced drift. The reference gas and a gas to be measured are introduced respectively into gas chambers 211 and 215 and electro-motive force that corresponds to oxygen gas concentration ratio develops between electrodes 41 and 45.
