USER MANAUL MGAprime Q The Analyzer is designed for the gas analysis of flue gases, MGAprime-Q as they are emitted from gas/oil burners, engines, or heating and power appliances. The analyser is intended to support the user in control and indicative measurements in an efficient, accurate and reliable way.
USER MANAUL MGAprime Q 2.2. About us The analyser is produced by the MRU GmbH in Neckarsulm, Germany (Founded in 1984), a medium sized company that is specialised in developing, producing and marketing high quality emission monitoring analysers. MRU GmbH produces a wide range of instruments, from standard analysers up to tailor made industrial analysers.
USER MANAUL MGAprime Q Description 3.1. Task The main task of the analyser is to analyse flue gases, as they are emit- ting from incinerators or engines. • The analyser is optimized for this purpose and includes all com- ponents from the gas sampling probe to data processing.

USER MANAUL MGAprime Q Measurement 6.1. Prepare measurement CAUTION Acid from the condensate Acid burns may result from weakly acidic liquids from the condensate. ► If you come into contact with acid, wash the area im- mediately using a lot of water.
USER MANAUL MGAprime Q ATTENTION When measuring with coiled heated hose line, the hose line is destroyed due to strong heat development. ► Roll out the heated hose line completely for each measurement. ► Unroll the heating hose. ► Connect the heating hose.
USER MANAUL MGAprime Q ► Ensure that ambient fresh air can be sucked in at the Fresh air inlet port (11). Consider to connect a hose leading fresh air to analyser. The flow rate of the gas should be within 60ln/h.
USER MANAUL MGAprime Q Attach clip-on filter If you operate the analyser without a heated hose, dirt may collect in the gas inlet. ► In this case, plug the supplied clip-on filter onto the gas inlet (12). Controlling Filters The filters (probe filter and round filter) must be checked before and after each measurement.
USER MANAUL MGAprime Q Connecting Acid Dosing Unit APE See also Chapter 3.9 Acid injection, page 18. CAUTION Acid from the condensate Acid burns may result from weakly acidic liquids from the condensate. ► If you come into contact with acid, wash the area im- mediately using a lot of water.
