摘要
Apparatus for automatically taking measurements and samples of gas during the operation of shaft-type furnaces, the apparatus including a gastight housing sealingly connected to the wall of a furnace and carrying within it a horizontally-disposed probe mounted for reciprocal movement through the wall and means to move the probe reciprocally. The measurements and samples are withdrawn from the housing through a sealed passage. The movement of the probe is controlled by a drive device disposed outside the housing and communicating with the probe mount through sealed passages in the housing.
