Gas detection apparatus and method

摘要

A gas detection chamber in which a gas sensing element is provided to detect a component of a gas allowed into the gas detection chamber is heated by a heater, and an output of the heater is regulated by a heater regulator. The heater regulator is adapted to cause the heater to continue to heat the gas detection chamber (preferably but not necessarily, the output of the heater is caused to lower) when an anomaly detection device detects an anomaly of the gas sensing element.
