1. Description
The Aeroqual AQM60 Environmental Station is a custom-built ambient air quality instrument. It’s platform is
configurable to measure common air pollutants including ozone (O3), nitrogen dioxide (NO2), carbon
monoxide (CO) and sulphur dioxide (SO2) as well as particulate matter (PM10, PM2.5) and meteorological
parameters such as temperature, humidity, wind speed and direction.
The AQM consists of an enclosure typically containing a control module, power module, thermal
management system, gas treatment module, a number of gas sensor modules, a RH/T sensor and
associated cabling and plumbing.
Note 1: The placement of individual modules will vary depending on the user configuration
Note 2: AQM60 units dispatched from July 2014 will also include an internal air duct (Refer to Section 1.8)

1.1. Control Module
The control module is the interface between the RS485 sensor bus and data communication links. It contains
a display, a SD data card which logs data, a RS232 serial connector for external communication, a bus
connector for internal communication with the sensor modules and a cable connector for the Sensirion
Humidity and Temperature sensor (if fitted).
The AQM60 is supplied with a RS232 to USB adapter fitted between the Control Module and an external
USB socket fitted at the side of the enclosure. This enables the user to perform a wide range of functions
over the USB connection, without needing to open the enclosure door, such as data logging and various
system checks using the supplied Aeroqual AQM60 PC software
Note: The driver for the RS232 to USB adapter is in the software CD which comes with the
instrument.
1.2. Gas Treatment Module
The Gas Treatment Module controls the gas sampling. Inlet air is filtered through a 5 μm membrane filter and
enters the Gas Treatment Module via either the sample or zero air ports. The air is then distributed via a
PTFE manifold to the gas modules. A solenoid controls the air path which can be switched from the directly
sampled ambient air to air which has passed through internal scrubbers (zero air) in order to check the
baseline readings of the gas sensors.

The Gas Treatment Module also contains a diaphragm pump which draws air through the gas modules. The
sample flow rate is controlled by a bypass screw fitted between the vacuum and pressure sides of the pump.
Note: If the AQM60 has an AirCal 8000 installed the zero air scrubbing material is located in the
AirCal module not the GTM.
1.3. Gas Modules
An example of a gas module is shown below. All modules are mounted onto the base plate using 4 or 2
bolts. They can be either full size or half size modules depending on the gas. Inlet and outlet tubes are

1.5. Compressor
The cooling system is a compressor refrigeration unit which is mounted at the base of the AQM60. It is a
self-contained system that provides cooling via the base on the AQM. The compressor system and inlet can
be accessed by releasing the two clips on the side of the AQM and rotating the housing upwards.
1.6. Power Module
Two Meanwell HLG240-12A 192W 12V Single Output Class 2 with PFC Power Units are mounted on the
outside of the enclosure. One powers the compressor and the second powers the modules. It has features
including universal AC input (90-280VAC) and IP65 rating.
1.7. Humidity and Temperature Sensor
The Humidity and Temperature Sensor is a Sensirion single chip device which contains a capacitive polymer
sensing element for relative humidity and a band-gap temperature sensor. More detailed specifications are in
the table below. The temperature and humidity sensor is housed in a connector located on the bottom of the
enclosure. It is connected directly to the Control Module.

1.8. Internal Air Duct
AQM60 units dispatched after July 2013 will include an
internal air duct (chimney). The chimney is a new
feature to improve thermal stability inside the AQM60
base system. Changes to both the heating and cooling
sub-systems ensure optimum airflow around the
enclosure, minimising thermal gradients thus
temperature effects on the sensors. This optimised
airflow has been coupled with enhancements to the
thermal measurement and control sub-system allowing
an even tighter temperature control ban.
The chimney will come pre-installed. However, there will
be times when the chimney may need to be removed
for servicing.
To remove the chimney the two screws, that connect
the chimney to the fan grill on the base of the
enclosure, need to be removed. The chimney should
then slide out and the two connectors behind can be
easily disconnected.
Note 1: The chimney is stuck to the side of the enclosure with double sided tape which may need to
be replaced when removing/replacing the chimney.
Note 2: The NOx/NO2 module can be removed without taking out the chimney by undoing the
mounting plate screws completely and sliding the module out.
1.9. Auxiliary Module (Optional)
The auxiliary module acts as an interface between third party sensors and the AQM60 communication bus.
It is configured with different operating modes which can be selected by using the dipswitches located on the
side of the module. Aeroqual has integrated a number of third party sensors and is able to supply the
auxiliary module preconfigured for your sensors.

1.12. Pneumatic Connections
The airlines and connections are shown in the figure below for a three gas AQM. The sample gas passes
into the Gas Treatment Module (GTM) and is distributed to the sensors via a PTFE manifold. The gas
modules sample from the PTFE manifold via a central pump located in the gas treatment module. The
solenoid can switch between the ambient air sample and air which has passed through an absorbent
scrubber for baseline measurements. The sample inlet tubing is PTFE tubing which is inert and smooth
walled. The module exhaust tubing is Tygon 3603 PVC tubing.
Note: The ports on the manifold which are not used must be capped off to prevent leaks.
An adjustable bypass valve is included between the vacuum and pressure side of the pump. This is to allow
an adjustment to be made to the module flow rates and to relieve the excess pressure placed on the pump
when only one or two modules are installed.
The total sample flow rate will be dependent on the number of gas sensor modules in the AQM. All module
flows are controlled by critical orifices located within the sensor modules. See Section 7.3.3.for expected flow
rates.

2. Installation and Commissioning
The purpose of this section is to enable the user to correctly assemble, commission, and install their AQM.
Undertaking the commissioning procedure correctly is an important part of the product
transfer process and customer acceptance. It confirms that you have received the product in
good working order and it has been shipped to you without damage.
The full commissioning process will require gas calibration and flow equipment (not supplied with the AQM).
In the absence of gas calibration and flow measurement capabilities, measurement of outside air over a 24
hour period and comparison of this data with measurements from a local “reference” air monitoring station
will provide evidence of correct span operation.
2.1. Unpacking
a) Examine the Shockwatch label on the side of the shipping box. If the indicator is red do not refuse
shipment. Make a notification on delivery receipt and inspect for damage. If damage is discovered,
leave item in original packaging and request immediate inspection from carrier within 15 days of
delivery date (3 days international).
b) Verify the serial number label on the documentation matches the serial label on the AQM (located on
inside of enclosure).
c) Verify that all components have been shipped as per the packing slip. Contact your Distributor or
Aeroqual if you suspect any parts are missing.
d) Unpack the AQM.
e) Remove all internal shipping/packaging material from the AQM enclosure.
f) Retain the packaging.
Note: Always transport the AQM in the cardboard box and two piece aluminum skins with foam
packing provided to avoid breakages. Wrap all peripheral assemblies in their original packaging also.
The AQM is a sensitive instrument and should be transported with care.
2.2. Assembly
2.2.1. Connect Mains Power
Caution: The high voltage mains supply must be wired by a certified electrician in
compliance with local electrical regulations.
Locate the 3 port junction box on the outside of the AQM cabinet:
Unscrew from the enclosure
Remove the three gland nuts
Insert a small flat bladed screwdriver to lever the retaining clips, on each side where indicated
Wire a mains electrical cable to the terminal block provided (Live, Ground and Neutral).
Close the lid to the 3 port junction box and replace the three gland nuts.

2.2.2. Connect Inlet Sub Assembly
Once the AQM60 has been connected the inlet sub assembly needs to be
installed to prevent unwanted materials, such as water and dust, being drawn into
the instrument. The sub assembly pipe is connected to the inlet at the top of the
AQM60 using a Kynar gland. The pipe needs to be securely inserted into the
Kynar gland and then the fitting needs to be tightened.
Ensure the two piece ferrule set is present inside the Kynar gland before screwing
it on, and be sure the orientation of the two pieces is correct as shown in the
image below. Failure to do this could result in a leak or could lead to water
entering the sample tubing which will permanently damage the sensor modules.

2.2.4. Connect third party sensors (Optional)
Third party sensors such as the Vaisala Weather Transmitter WXT520 or Gill Windsonic are connected to
the unit using the external plug. This is located on the right hand side of the enclosure. Once connected, they
should automatically start reading.
Note: Turn off the AQM60 before plugging in any external third part sensor.
2.3. Initial Commissioning
The objective of the initial commissioning process is to enable the user to gain knowledge in the operation of
the instrument and to demonstrate that it is operating correctly prior to a remote installation. The process
consists of a set of tasks that check that the AQM is operating correctly.
Equipment required:
AQM Logbook
Computer with Aeroqual AQM V6.X PC software loaded
Flow meter covering the range 0-2.5 LPM
Zero air source
Span gases corresponding to the sensors in the AQM
Calibrator or gas flow meters for generating suitable span gas concentrations
Humidifier (Nafion tubing supplied with AQM)
Note 1: Before starting the commissioning process it is important that the AQM is fully warmed up by
running overnight and sampling either outside ambient air or indoor air with an activated carbon
filter connected to the inlet.
