Abstract
An apparatus and method to measure combustible gases using a catalytic sensor includes: housing the catalytic sensor in a flow-through chamber isolated from a volume of ambient gas; periodically drawing into the chamber a sample of the ambient gas; burning on the catalytic sensor and in the chamber the combustible gas in the sample of ambient gas, e.g. essentially until the completion of burn out, and measuring the plurality of output signals of the sensor synchronously with the interrupted ambient gas sampling while burning the sample on the catalytic sensor.
