摘 要：
This invention provides apparatus for determining the concentration of a
selected gas, e.g. hydrogen, nitrogen or oxygen, in molten metal of known
temperature and composition (other than dissolved gases). A tubular probe is provided having an outer sheath
impermeable to the metal, constructed from a gas permeable refractory or cermet (1) for immersion in the melt, means (3) for passing a gas of known composition through the probe such as to realise an equilibrium condition, via the sheath, with the gas dissolved in the melt and means for analysing the equilibrated gas collected from the probe whereby to determine the concentration of the selected gas in said melt. 主权项： CLAIMS/n
