A combustible gas sensor with a calibration test adaptor. A standard combustible gas sensor attached to a transmitter in transmitter housing has a body portion attached thereto which is adapted to receive and slowly distribute test gas in the vicinity of the combustible gas sensor. A flexible bladder fastened to the main body portion receives the test gas, inflates, and slowly releases the test gas through a sintered stainless steel plug mounted in one end of the flexible bladder.
