Title:
ガス検知シート
Document Type and Number:
Japanese Patent JP4699737
Kind Code:
B2
Abstract:
This invention provides a gas detecting sheet, which can detect a plurality of gases at the approximately same time, so as to be able to easily detect which of the gases is leaked, in an environment where the leaks of a plurality of kinds of gases are estimated, and discloses the gas detecting sheet which can measure the concentration of a detection target gas in a environment where an interference gas exists especially. Proper intervals are set for a base plate 2, and a plurality of gas detectors 3 are formed, and the kinds of the target gases to be detected by those gas detectors 3 are made different. This base plate 2 is designed so as to be attachable to and detachable from a gas detecting unit 30 for measuring the gas concentration. Also, when one gas detector 3 is used to detect the detection target gas and the other gas detector is used to detect the interference gas, the detector for the detection target gas determines the total concentration of the detection target gas and the interference gas. Thus, when the concentration value determined by the detector for the interference gas is subtracted from this concentration value, the concentration of the detection target gas is determined.
