Abstract : A gas comparison probe contains first and second sensor elements isolated from each other. Air is drawn across a surface to be monitored and directed onto the first sensor element. Air is drawn from a location spaced away from the surface to be monitored and directed onto the second sensor element. A flow constrictor in the air flow path to one of the sensor elements is used to calibrate the outputs of the two sensor elements under known conditions before attempting to monitor air flow which may contain a gas to be detected.
