"Processes to produce copper or other metal and to produce a body of immersion probe for use in a system for measuring gas.The apparatus gas analyser for the determination of gas concentration of a metal in fusion, and body of the probe immersion. A process for improving the manufacture of metals such as iron and copper, which uses a measurement system of a gas metal (13) to measure the gas content of the metal (2),Specifically, hydrogen content, and to control the manufacturing process of the metal based on the value of the gas content.The gas analyser (13) comprises a preferred body immersion probe enhanced long-term (21) and an analyzer (14) in which the probe body (21) is immersed in the molten metal (12) and a GThe carrier (23) is circulated through the probe (21) and analyzer (14).The carrier gas (23) draws gases which diffuse into the interior of the.Or are formed in the probe body (21) and this gas mixture is electronically compared with a reference value to provide a measure of the gases in the molten metal (12) and the process is controlled(24) on the basis of the results of the analyzer.
