A furnace for melting metal by the Joule effect to enable extraction of gases contained in the metal comprising a hollow tubular body which constitutes a heater resistor clamped between two electrodes, and a separate crucible for the metal which is supported within the tubular body and out of direct contact with the electrodes.

Furnace for melting metal by the Joule effect

Method and apparatus for measuring the gas in a metal sample wherein a reference circuit has gas flowed therethrough from a source, a detection circuit including a degassing chamber therein has gas flowed therethrough from the same source, the reference and detection circuits leading to comparison cells of a catharometer and then to a common measuring circuit, and a complementary circuit is connected to the detection circuit with a gas flow therethrough to selectively apply a protective gas curtain to the degassing chamber during introduction and removal of the sample.
