|1. (WO2018222803) GAS DETECTION APPARATUS|
|Applicants:||NGK SPARK PLUG CO., LTD.
|Title:||GAS DETECTION APPARATUS|
A gas detection apparatus for detecting the concentration of a first gas component contained in a gas under measurement includes a gas conversion section for converting the first gas component to a second gas component, a gas detection section whose electrical characteristics change with a change in the concentration of the second gas component when the gas detection section is in an activated state, and a detection state setting section. During a detection period, the detection state setting section sets the state of gas detection by the gas detection section to a detection executed state in which the gas detection section can detect the second gas component. During periods which are not the detection period, the detection state setting section sets the state of gas detection by the gas detection section to a detection suspended state in which the gas detection section does not detect the second gas component.
