Abstract
A hydrogen measuring apparatus comprising two gamma thermometers. Both gamma thermometers are mounted adjacent and parallel to each other. Each is provided with a plurality of annular enclosed spaces formed in an elongated rod. Each annular space is provided with a hot junction of a difference thermocouple. The annular spaces of one of the gamma thermometers is either filled with a gas other than hydrogen, or surrounded by a hydrogen blocking material to prevent hydrogen contamination of the annular spaces. The annular spaces in the other gamma thermometer are placed in a vacuum and become contaminated with hydrogen. By comparing the power generation readings of the two thermometers free hydrogen partial pressure can be calculated.
