摘要： A method and apparatus for measuring the concentration of gas, such as hydrogen, in a liquid, such as molten aluminum, without requiring a bias or adjustment to compensate for variations in ambient conditions, such as humidity. A measurement system includes a probe connected to an analyzer with a housing enclosing a pump assembly. The measurement system may include a climate-controlled environment substantially devoid of ambient humidity and surrounding at least the pump assembly. A modified pump assembly includes at least one seal, at least one diaphragm and at least one gasket made from a material compatible with hydrogen and substantially unaffected by ambient humidity. A method of use is also disclosed.
