ABSTRACT:
A hydrogen probe system measuring hydrogen gas produced in the corrosion of steel, both in volume and rate, with a relatively simple construction, rapid installation at any location and trouble-free operation for extended periods of time without supervision. The probe system has a ferrous metal body enclosing a cavity collecting hydrogen gas metered through a capillary port into a background liquid contained in a sample cell thereby forming discrete, uniform-dimensioned bubbles. A detector senses the release of these bubbles and provides a representative output signal to an output means giving a readout of the hydrogen gas bubbles being released within a selected time interval.
