3Intended use
The main task of the analyser is the gas analysis for
Emission control measurements on large combustion plants and
engines.
•The analyser is optimized for this purpose and includes all
components from the gas sampling probe to data processing.
•The analyser also performs other measurement tasks such as
pressure and temperature measurement or measurement of
flow velocity.
For an actual overview of the available options please visit the MRU
homepage or contact our sales representatives.

4.3. Acid Dosing Unit APE (Option)
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
immediately using a lot of water.
►Note the safety data sheet for phosphoric acid (10%).
►Consider to connect a container to the condensate
out port
Phosphoric acid (10 %) is injected into the analyser using the
Acid Dosing Unit APE (# 12076 Injection MGAprime-Q Set).
The injection of phosphoric acid (10 %) is necessary for a correct
measurement.
•The injection guarantees constant conditions in the gas cooler, so
that you can measure dry or humid flue gas.
•The use of phosphoric acid (10%) reduces losses of SO2, NO2on
the humid surfaces of the gas cooler.

6Measurement
6.1. Prepare measurement
Operating temperature
The internal gas cooler operates at 4°C, which is the dew point of the
sample gas to the sensors. Components along the gas line may be dam-
aged if they are colder than 4°C and condensation appears internally.
Therefore, if the analyser has been stored very cold below 0°C, it is
essential to wait for the analyser to warm up in a warm environment in
order to avoid such condensation! In such cases, take a typical warm-up
time for the instrument of one hour into account, especially when wet
flue gases are to be measured.
If the operating temperature is not within the permissible range, a
corresponding message is displayed.
ATTENTION
►Operate the analyser in a standing position only.
See also chapter 4.4 Connectors, S.6.
►Set up and operate the analyser only as shown in the
illustration.
►Never operate the analyser in a lying position.
The analyser may otherwise be damaged.

MRU GmbH, D-74172 Neckarsulm 9 / 12
Power supply
The analyser can be operated with an internal battery to warm up the
instrument or to use internal instrument functions. A mains connection
is required for the measurement including heated gas sampling probe
and heating hose.
Opening the transport bag
►Open the transport bag to get access the control panel (1).
►Open the transport bag to get access to the left side. (2).
►Open the ventilation flap (3).
Connections to the analyser
See also Chapter 3 Analyser, Probe, Acid Dosing Unit APE and . S.
3.
►Connect the gas sampling probe to Sample gas inlet port (12) (gas
coupling and round plug).
►Note that acidic condensate as well as phosphoric acid is discharged
from the condensate out port (9). Consider to connect a hose or
collecting container to the condensate outlet when
appropriate. Ensure that the empty volume of the collection
container is sufficient (24ml/h). The hose must not be closed and the
collection container must have a ventilation opening.
►Please note that measuring gas may leak at the analyser side or at
the Sample gas outlet port (10)
►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.
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.

Connecting Acid Dosing Unit APE (Option)
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
immediately using a lot of water.
►Note the safety data sheet for phosphoric acid (10%).
►Consider to connect a container to the condensate
out port
NOTE
Phosphoric acid (10%) is not included in the scope of
delivery.
Phosphoric acid (10 %) must be procured by the
operator.
►Check the remaining contents of the acid tank
before measurement.
►Connect a collection container to the condensate outlet.
►Plug the AUX-connector into the analyser.
The AUX-connection cable ensures that no phosphoric acid (10 %) is
injected into the analyser when the pumps are switched off.
►Plug the couplings of the connecting hose into the connection
nozzle of the Acid Dosing Unit APE (2x outlet to device).
►Plug the couplings of the connecting hose into the connection
nozzle of the analyser.
NOTE
You do not have to pay attention to any special
arrangement of the couplings between the Acid
Dosing Unit APE and the analyser.
Make sure that the hose connectors click into place
audibly.
►Plug the coupling of the connecting hose to the acid tank into the
connection nozzle of the Acid Dosing Unit APE (Input 10 %
phosphoric acid).
Plug the cable socket of the mains cable into the Acid Dosing Unit
APE (Main).
►Plug the power cord into the socket.
At the end of the zero-point measurement, phosphoric acid (10
%) will be injected.

The control lamp lights up green as soon as phosphoric acid
(10 %) will be injected. The control of the acid dosing unit APE
begins 40 minutes after the analyser is started
6.2. Take a measurement
►Touch the menu Measure.
