be able to read instructions as needed.
Please ensure to hand over all documents to when handing the analyz-
er over to others.
1.1 Intended use
The Analyzer MGAprime is designed for the gas analysis of ue gases,
as they are emitted from gas/oil burners, engines, or heating and power
appliances.
The instrument is intended to support the user in control and indicative
measurements in an ecient, accurate and reliable way
The analyzer is specically not intended as a safety device or personal
protective equipment; it should not be used as a warning device to warn
people against the presence of harmful gases.
The instrument was manufactured according relevant normatives and
regulations. It has to used within it’s intended use.
The Instrument must not be modied from the design or safety engineer-
ing.
Modications of any kind by the user will render the declaration of
conformity.
Syntax
Please note that this manual makes use of the scientic notation of gases
(NO2), while the instrument itself and it’s screen shots display the gases in
upper case letter only, i.e. (NO2).
This instrument meets the requirements of the valid
European and national regulations.
You can ind the declaration of conformity in the ap-
pendix.

3.1 Task
The instrument is designed for the gas analysis of ue gases, as they are
emitted from gas/oil burners, engines, or heating and power appliances.
The instrument is intended to support the user in control and indicative
measurements in an ecient, accurate and reliable way
The instrument provides a full set of all equipment and sensors required
for a emission control measurement:
yheated probe incl heated lter
yheated sample line
ygas conditioning unit including lters and gas cooler
ygas pump and ow control
ygas sensors
Available accessories include sensors for temperature or ow measurement.
The user interface allows for a modern and intuitive way to operate the
instrument. Running a commercial LINUX operating system, it allows as
well for lot of options for data transfer and storage.
For an overview on all available options please refer to the company’s
home page or sales representatives.
3.2 Gas ow diagram
The analyzer draws a sample of the ue gases from the duct using a built-
in gas pump through the probe is cleaned and dried using a gas cooler
and built-in lter and analyses the extracted gas with electrochemical
and NDIR sensors.
Draft and temperature are measured at the tip of the sampling probe.
