    Innovative measurement of mercury in flue gases

    The MERCEM300Z extractive mercury gas analyzer monitors Hg emissions in flue gases with high reliability down to the smallest measuring ranges. Thanks to a range of housing variants, the MERCEM300Z is suitable for both application in climate-controlled analysis containers and outdoors under exacting ambient conditions. The complete extractive system is designed to meet national and international official requirements.
