The atmosphere must be just right

The MINESIC700 TBS tube bundle analyzer system is ideally suited for monitoring the mine atmosphere in shafts and goafs in underground coal mines. The system extracts gas from different parts of the mine via specially designed polyethylene tubes that are connected to a powerful gas sample pump. The system also comprises purge pumps, certified flame arrestors, and gas conditioning components. The gas sample is analyzed with approved NDIR gas analyzers and paramagnetic oxygen analyzers.
