摘要：A method and apparatus for measuring the concentration of gas, such ashydrogen, in a liquid, such as molten aluminum, without requiring a bias or adjustment tocompensate for variations in ambient conditions, such as humidity. A measurement

system includes a probe connected to an analyzer with a housing enclosing a pumpassembly. The measurement system may include a climate-controlled environmentsubstantially devoid of ambient humidity and surrounding at least the pump assembly. Amodified pump assembly includes at least one seal, at least one diaphragm and at leastone gasket made from a material compatible with hydrogen and substantially unaffectedby ambient humidity. A method of use is also disclosed.
