The MCS300P HW is a hot/extractive analyzer system for measurement of gases. It measures IR- or VIS-active components with variable measuring ranges for monitoring and controlling of combustion and flue gas conditioning. The heated system components prevent a temperature drop below the water and acid dewpoint. This results in lower maintenance and higher reliablity and long-time stablity of the system, also under rugged and demanding conditions. Automatic adjustment functions, easy operation concept and modern communication protocols results in a quick and easy integration into a local control system network.
