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 wherein hydrogen gas is collected under superatmospheric pressure. The accumulated hydrogen gas is periodically vented by a valve operated between two pressure set-points with a "snap action" function by a control mechanism. Each actuation of the valve is a readout function of hydrogen gas accumulating in the cavity representing total gas volume or the rate of gas generation.
