ABSTRACT:
A stack gas analyzer with a sampling probe mounted in the stack has a subsystem for supplying calibrating gases and blanking air to one or more gas analyzers either through the probe or directly. The rates of flow in the system are established to permit the analyzers to be flooded with calibrating gases or blanking air at any time without interrupting the operation of equipment which normally conveys stack gases to the analyzers.
