Aeroqual Dust Profiler User Guide
1. Description Aeroqual’s Dust Profiler is a user friendly instrument designed to provide continuous particulate
measurement of PM10, PM2.5, PM1, and TSP. It uses an optical particle counter to count and classify
particulate matter according to size. The instrument then converts the size distribution into a mass
measurement.
The instrument includes an embedded PC and two powerful software systems, Aeroqual Connect
and Aeroqual Cloud. There are numerous additional options available, including wireless
communications, SMS and email notifications, alarm functionality and the integration of factory tested
weather sensors. The instrument is packaged in a robust, lockable enclosure and is light enough for
one person site installations. The ease of installation, as well as the extensive range of possible add-
ons, enables the unit to be used in a wide range of applications.
Note: 12 VDC Power Supply mounted externally at base

Aeroqual Dust Profiler User Guide
1.1 Optical Particle Counter
Aeroqual uses an OEM optical particle counter from Met One
Instruments. The particle counter uses scattered light to
measure and count particles. Light from a laser diode is
collimated to illuminate the aerosol sample flow. When a
particle is present it scatters the incident laser light which is
detected using a 60o solid angle elliptical mirror at right angles
to the laser beam. The amount of scattered light is converted
to a voltage pulse and the amplitude of the pulse is calibrated
to a particle diameter. The particles are thus assigned on the
basis of size to one of eight channels.
1.1.1 Electrical connections
The connections to the optical particle counter are at the bottom of the unit. There is also a LED which
turns red if there is a fault condition (see Troubleshooting section). The optical unit also requires an
earth wire to be connected between the housing and the 0VDC line on the power bus. Please check
that this is fitted if the unit has been replaced.
1.1.3. Inlet Heater
The Dust Profiler uses a 12 V heater on the sample inlet tube to reduce the humidity of sampled air to
prevent particle growth and fogging of the particle counter optics in high RH conditions. The inlet
should always be heated.
1.1.4. Inbuilt Filters
The Particle Counter engine requires two filters which are installed externally. They are designed to
provide protection to the pump and optical window. Both filters should be replaced at specified
intervals (See Maintenance Section 5). The BQ filter is the sheath air filter and the DQ filter is the
sample air filter.

The pump and pneumatics are easy to access for servicing and replacement:
1.3. Power Module The Dust Profiler internal power requires regulated 12 VDC to
maintain a constant pump speed. An external mains to
12VDC power supply (Meanwell HLG80-12A 60W 12V) is
fitted on the outside of the enclosure and this will allow
connection to mains supply.
Note: If you wish to run the Dust Profiler on solar power
you will need to use a DC-DC convertor in order to supply a regulated 12 VDC for the Dust
Profiler
1.4. Auxiliary Module (Optional)
The auxiliary module acts as an interface between third party sensors and the Dust Profiler
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.

1.5. Crevis PLC (Optional)
The Dust Profiler can be configured with a Crevis controller and
Crevis output cards. These output cards are designed to convert
the Dust Profiler’s digital values to analogue outputs. The cards
offer 4 x 4-20mA and 2 x relay outputs which can be user
configured in Aeroqual Connect or Aeroqual Cloud.
The Crevis controller type is Modbus NA-9171 and the mode type
is Modbus RTU. The outputs cards are ST-4214 for the 4-20mA
outputs and ST-2747 for the relay outputs. Further information
and specification on both these cards can be found on the USB
stick provided with the instrument.
The Crevis is powered by the Dust Profiler 12V power supply. As
a result the maximum load is 300ohms. If a higher maximum load
is required an external 24V power supply can be used to power
the Crevis. This will allow for a maximum load of at least
500ohms.

Aeroqual Dust Profiler User Guide
3. Connecting to the Dust Profiler
3.1. Initial Connection using Aeroqual Connect
Aeroqual Connect is the standard user interface which comes with the Dust Profiler and allows the
user to be connected directly to the instrument. It can be accessed via WIFI, Ethernet or a cellular
modem. The on-board computer has an Ethernet output for direct wired connection. Alternatively,
connection can be made over WIFI by connecting to the Dust Profiler network (Access point mode), a
local network (Client mode) or via a modem.
The default setting of the instrument when first purchased will be to connect to Aeroqual Connect via
access point mode. Access point mode allows connection to the Dust Profiler via the Dust Profiler
network signal which will show up on a laptop, tablet or smart phone within range. This type of
connection will most commonly be used when working on the instrument in the field. However, it will
also be used to initially connect when the instrument first arrives.
Connecting by this mode will mean the user’s device is connected via WIFI directly to the Dust
Profiler. There will be no internet connection on the user device when using this option. To connect
you will need to select the Dust Profiler WIFI network and enter the password.
Note: The default user name and passwords can be found on Page 1 of the log book.
Once a WIFI connection has been made Aeroqual Connect can be accessed via the PC browser by
entering the IP address 10.10.0.1 in the address bar. The login screen below will then be displayed.
MRK-D-0021 V1.0 Page | 17
Aeroqual Dust Profiler User Guide
1. An Aeroqual Connect login name and password will be provided when Aeroqual Connect is
first purchased. If you do not know your login details please contact [email protected].
2. Once you have logged in the homepage will be displayed.
Note 1: Different applications will appear depending on the user accessibility configured for
your account.
Once the first connection has been made (via access point mode) the WIFI communications can be
configured according to how you would like the system to respond. This can be done via the settings
tab under the Configure Instrument application.
3.2. Connection Options
3.2.1. Client Mode
Client mode allows connection to the Dust Profiler via a local network (e.g. your office network). If
there is a local WIFI or LAN network available at the Dust Profiler installation site then the instrument
can be set up to connect to this network. This might be the case if the Dust Profiler is installed on the
perimeter of an industrial site and the WIFI network extends out to where the unit is installed.
Alternatively the Dust Profiler can be connected to the local network via an Ethernet cable from the
instrument to the local router using the Ethernet output on the base of the Dust Profiler.
When the Dust Profiler is connected to your local network (such as your office WIFI network), the local
network will automatically assign a local IP address to the instrument. The IP address assigned to the
instrument can be found in the Configure Instrument application when logged in via Aeroqual Cloud.
Entering this IP address into the web browser will open Aeroqual Connect for that specific instrument,
assuming you are within the local network.
If the local network allows outside access (e.g. via VPN), connection to the Dust Profiler can be made
from anywhere in the world. In the more common scenario where the local network does not permit
outside access you may still connect to the Dust Profiler using Aeroqual Cloud through the internet
because most local networks permit internet access.
To configure the Dust Profiler to use client mode the instrument needs to be configured via the
settings tab under the Configure Instrument application.
1. The WIFI mode needs to be set to Client
2. The WIFI SSID (local network name) needs to be entered (e.g. your office WIFI name)
3. The WIFI password needs to be entered (e.g. the password for your office WIFI)
Note 1: Before changing the WIFI settings it recommended that you have another connection
to the instrument established – typically by connecting the instrument to your LAN using the
Ethernet connection and using Connect with the LAN IP address.
Note 2: Once WIFI client mode is set up Aeroqual Connect will automatically disconnect from
WIFI access point mode. Connection will then need to be made via Aeroqual Cloud (See
section 4.5) to see the local IP address assigned to the instrument.
Note 3: If the local WIFI network password changes or you enter it incorrectly, you could be
locked out of the Dust Profiler. If this happens you will need to re-set the Dust Profiler back to
factory default settings, which puts the Dust Profiler back in to Access Point mode with a
default password. You can then reconfigure the settings correctly. Contact
[email protected] for information on how to perform this process.

Aeroqual Dust Profiler User Guide
3.2.2. Cellular Network Connection
If the Dust Profiler has an IP modem installed in the instrument a connection can be made via a
cellular network. This option is useful when remote access to the Dust Profiler is required but there is
no local network signal at the instrument installation site so client mode cannot be used. Aeroqual will
preconfigure the modem and load a default APN (Internet). This may work without having to be
changed. If set up is still required, only the APN, User name and Password needs to be modified.
Note1: A local data telecommunications contract and SIM card is required.
Note 2: The Dust Profiler uses approximately 20 megabytes per sensor per day. This is an
estimate for a Cloud connection and can vary wildly depending on the cellular provider.
Note 3: Using Aeroqual Connect via the modem will incur higher data usage.
1. The IP modem will need to be set up by plugging directly from the modem Ethernet port to a
laptop Ethernet port and browsing to 192.168.127.254.
2. In the menu select Network Settings GSM GPRS Settings and configure settings as per
picture below. Contact your SIM card provider to obtain full ATD and APN settings. Click
Submit button.
3. Unplug MOXA unit from the network and plug it into Dust Profiler embedded PC. Restart Dust
Profiler embedded PC and modem.
4. In the Configure Instrument application the Ethernet Mode setting needs to be set to Auto
(DHCP). WIFI mode should still be set to Access Point so a direct connection can still be
made.
5. If you do not wish to use Aeroqual Cloud, a DynDNS service will need to be set up to create a
permanent web address for the Dust Profiler.
6. A Dyn account can be created at https://account.dyn.com/cart/?via=upgrade-now
7. Log in to your account and add a new host name:
MRK-D-0021 V1.0 Page | 19
Aeroqual Dust Profiler User Guide
8. Go back to MOXA modem configuration interface, and choose System Management - > Misc.
Network Settings - > DDNS. Select enable and DynDns.org. Input the host name created in
Dyn account, user name and password as well for the Dyn account. Then click Submit button,
Save and Restart. Now the modem should be ready to be connected via host name.
9. Enter the set up web address into the web browser to access Aeroqual Connect.
Note 1: No data is stored on the DynDNS server. It only acts as an access point to
communicate with the Dust Profiler.
Note 2: In some countries the telecommunications provider will block incoming requests to
the modem. If this is the case DynDns will not work with regular SIM cards. Contact your
telecommunications company about using an open APN or use a private APN.
3.3. Aeroqual Cloud When using Aeroqual Cloud, the user is connected to the Aeroqual Cloud server. The Dust Profiler
instrument is also connected to the Cloud server. The user connects to Cloud over the internet; the

1.7.1.1.1.1.1. Note 2: All checks should be carried out during the initial commissioning of the Dust Profiler
5.2. Maintenance Procedures
5.2.1. Sample Flow Check and Adjustment
A constant 1.0 LPM flow is essential to ensure monitor is measuring correctly. To measure or set the
flow perform the procedure below:
1. Remove the TSP head from the inlet and connect a 0-2.5 LPM volumetric flow meter to the sample
inlet. Ensure the flow meter is on a steady surface and the correct flowmeter port is connected to the
Dust Profiler inlet.
2. Adjust the position of the Sample flow adjustment valve until the flowmeter reads 1.0 LPM.
Note: The inlet should be connected to the TOP of the volumetric flow meter (negative flow)
Afterwards replace the inlet components with care making sure there is no leak.
MRK-D-0021 V1.0 Page | 31
Aeroqual Dust Profiler User Guide
5.2.2. Sheath Flow Check
The sheath flow is a constant stream of air which ensures the optics remains clean. It is important this
is working correctly to maintain the accuracy of the measurement. To check the sheath flow:
1. Remove the TSP head from the inlet and connect a 0-2.5 LPM volumetric flow meter to the
sample inlet. Ensure the flow meter is on a steady surface and the correct flowmeter port is
connected to the Dust Profiler inlet.
2. Check that the sample flow is 1 LPM, if not adjust Sample flow valve (see above).
3. Pinch the purge tubing to block flow through the purge. This will increase the sample flow. If
the sample flow > 2.0 LPM then the sheath flow is good. If the sample flow < 2.0 LPM then
there is a problem. Change the filters and check for a leak.
5.2.3. Leak Check
If the correct sample or sheath flow cannot be achieved, there may be a leak in the pump module or
engine. First check the entire flow system:
Remove exhaust connection from the base of the enclosure
Remove the TSP head and block the PM inlet.
Connected the pressure end of a flow meter to the exhaust tubing.
If there is no leak the flow should drop to zero.
If the flow does not drop to zero it suggests there is a leak somewhere in the system. To check the
pump module:
Remove the sample connection and cap off the module sample port.
Connect the exhaust port of the module to the pressure end of a flow meter.
The flow should drop to zero.
If there is a leak in the pump module the module will need to be sent back to the Aeroqual factory.
Please contact technical support.
If there is no leak in the pump module it is likely the leak is located in the engine. In this case, the
engine will need to be sent back to the Aeroqual factory. Please contact technical support.
5.2.4. Manual Zero Air Check
A zero air check can be carried out manually. To do this the TSP inlet needs to be removed and the
particle filter (supplied with the instrument) needs to be attached to the monitor. Ensure there is a
good seal around the inlet.
The filter will remove 99.99% of particulates from ambient air. Wait 5 minutes and then check the
readings on the control module. The reported value should be <2 µg/m3.
MRK-D-0021 V1.0 Page | 32
Aeroqual Dust Profiler User Guide
5.2.5. Filter Changes
There are two green filters installed in the Dust Profiler. They are designed to provide
protection to the pump and optical window. The filters will become dirty and must be
replaced periodically.
To do this, unclip the filters from the connectors and replace. Ensure the filters are
connected the right way in accordance to the flow arrow. These filters can be
purchased from Aeroqual. Please contact technical support for a quotation.
Note: BQ filter – Sheath air filter
DQ filter – Sample air filter
5.2.6. Inlet Cleaning
The TSP inlet can be dismantled by unscrewing the 3 screws and separating the head into two parts.
Use a lint-free cloth wetted with isopropyl alcohol to clean both the inside and outside of the inlet.

6. Mass Calibration
All particle monitors based on light scattering require a site calibration for optimum accuracy. This is
because the average density and light scattering behaviour of dust particles will vary from site to site.
This adjustment is sometimes known as a “K-factor”. Aeroqual recommends a site calibration be
performed at the time of initial installation and then every 6-12 months. Calibration is performed by co-
locating the Dust Profiler with a Reference Particulate Matter measurement system and adjusting the
Gain of the particle monitor so the average reading matches that of the Reference Instrument. A list of
Reference instruments can be found at: http://www.epa.gov/ttnamti1/files/ambient/criteria/reference-
equivalent-methods-list.pdf
Install the Dust Profiler beside the Reference instrument. Make sure both instruments are setup
correctly. Two procedures are given below depending on whether the reference instrument is a
gravimetric or continuous instrument.
Procedure overview for Gravimetric Reference Instrument
1. Weigh a reference filter and install into the Reference instrument.
2. Leave the Dust Profiler and Reference instrument running for at least 24 hours until a weighable
quantity of particulate matter sample has been collected.
3. Check the sample flows of both instruments to ensure they are within specification.
4. Remove the Reference filter and re-weigh
5. Download the Dust Profiler PM data for the calibration period.
Calculations
1. Reference Filter Weight of PM (ug):
PM(Ref) = (filter weight at finish) – (filter weight at start)
2. Volume of air sampled by reference sampler (m3)
Volume(Ref) = minutes of test * Flow Ref (LPM) / 1000
3. Calculate average reference PM density (ug/m3)
AvPM(Ref) = PM(Ref)/ Volume(Ref)
4. Calculate average PM (ug/m3):
AvPM(Dust Profiler) = sum(PM readings over test period)/number of readings
Procedure overview for a Continuous Reference Instrument
1. Leave the Dust Profiler and Reference instrument running for at least 24 hours
2. Check the sample flows of both instruments to ensure they are within specification.
3. Download the Dust Profiler and Reference instrument data for the calibration period Calculations
1. Calculate average Dust Profiler PM (ug/m3):
AvPM(Dust Profiler) = sum(PM readings over test period)/number of readings
2. Calculate average Reference PM (ug/m3):
AvPM(Ref) = sum(PM readings over test period)/number of readings
Calculation of Dust Profiler Gain
1. Calculate K factor
K factor = AvPM(Ref) / AvPM(Dust Profiler)
2. You should then apply this to the Gain Factor on all the PM channels.
new GAIN = old GAIN x K Factor

11. Mounting and Site Positioning Guidelines
It is important that the positioning of the Dust Profiler is suitable so as to yield data which is
representative of that specific location.
1.1. Mounting The Dust Profiler comes with 2x mounting brackets and 3x U-bolts for 2 inch poles. The same
brackets are used for both pole and wall mounting. To wall mount the Dust Profiler the brackets are
screwed into the wall instead of using the U-bolts.
For pole mounting:
1. Secure top mounting bracket at a suitable height using 2x U-bolts provided
2. Fix lower mounting bracket to the Dust Profiler chassis with screws
3. Hang the Dust Profiler on the top mounting bracket
4. Place U-bolt through lower mounting bracket
Note: Only one U-bolt is used to secure the bottom bracket
5. Add nuts and washers and tighten the bottom U-bolt into position
1.2. Inlet height If PM monitoring is related to human exposure, the sampling inlet height should be positioned
in the “breathing zone”. This is located between 2 and 15 meters above ground level.
If PM monitoring is related to specific emission sources, the position of the sampling inlet can
be more flexible. It is more important that there is no obstruction between the approaching air
from the emission source and the sampling inlet.
If more than one Dust Profiler, or any other particulate instrument, is being used at the site,
the height of the inlets should be uniform.
If the Dust Profiler inlet is the highest point at the site, a lightning rod must be installed to
prevent damage to the unit during electrical storms.

1.3. Measurement Interference The meteorological conditions of the site should be taken into consideration when positioning
the Dust Profiler. For example, there should be no obstruction to the air flow in the
predominant wind direction. A minimum clear sky angle of 120 degrees is recommended.
The inlet should be at least 1 meter away from any objects that could potentially influence the
airflow characteristics e.g. trees, vertical surfaces or walls.
Avoid overhead high-voltage cables which may cause electrical interference with the
sampling equipment.
Demolition/construction activities and change to normal transport patterns due to road works
etc. can significantly affect the data. Ensure a record of such events is kept to account for
unexpected peaks in concentration.
1.4. Safety The intended data capture rate should be considered when positioning the Dust Profiler. If
data capture above 90% is essential, the unit should be located in an area which has 24 hour
access available.
The positioning should allow for routine maintenance checks to be performed safely by
personnel.
If using a tripod, ensure the tripod legs are bolted to the ground to prevent the unit from
falling. Ensure the Dust Profiler is in a secure location to avoid vandalism or theft.
