1. A hydrogen probe system comprising:

  • a. a ferrous metal probe body adapted to be exposed to a corrodant, said body having an enclosed fluid-tight internal cavity for collecting hydrogen gas produced by action of the corrodant on said body;

    b. a sample cell containing a background liquid chemically inert and in which hydrogen has a relatively low solubility;

    c. capillary port means in said sample cell connected by a fluid channel to said cavity, and said capillary port means precisely metering discrete uniform-dimensioned bubbles of hydrogen gas into said background liquid;

    d. detector means sensing the release of hydrogen gas bubbles into said background liquid and providing an output signal representative thereof; and

    e. output means receiving said output signal and providing a readout of the hydrogen gas bubbles being released from said capillary port means.
