Abstract

A gas detecting apparatus is disclosed in which detection outputs from a plurality of semiconductor gas detecting elements different in gas detection characteristic from each other and previously-obtained characteristic values of the semiconductor gas detecting elements for a mixed gas are subjected to operational processing to detect one or more specified constituent gases contained in the mixed gas, and in which when the specified constituent gas is detected, the detection information is announced by some means, and also the supply of gas is stopped or a supply gas is diluted.
