Abstract

PURPOSE: Sensitivity changes and false operations owing to the contamination of measuring chamber window surface are eliminated and the gas detection of high reliability is accomplished by disposing in series the detecting vessel sealed therein with the gas to be detected at a low concentration and the detecting vessel sealed therein with the same gas at a high concentration and detecting the differential pressure produced when a gas enters the measuring chamber.
