COMTEC^® 6000 DustEx

Information

The standard InSitu analyzer system for use in dust explosion zones 21/22 is COMTEC^® 6000 DustEx. In accordance to the tough demands placed on measuring systems in high dust processes, the DustEx is ATEX certified to II 2D Ex tb IIIC T133°C/T141°C Db.

Being able to precisely determine the proportion of oxygen and CO_e in flue gas is the starting point for the safe and optimized operation of incinerators, as oxygen and CO_e are dependent to one another within a combustion process. Undesirable developments can thus be identified and rectified earlier, before any damage is caused.
The COMTEC^® 6000 DustEx is also available for O₂ only measurements.
