ABSTRACT:
Systems and methods for monitoring a heat treating atmosphere derive from at least one sensor placed in situ in the atmosphere a process variable, which is indicative of the ratio of gaseous hydrogen H2(g) to water vapor H2O (g) in the atmosphere. The systems and methods use the process variable, e.g., to control the atmosphere, or to record or display the process variable.
