Note 2: The above wiring connections are subject to change, please refer to the third party
sensor manuals for the latest wiring instructions.
Note 3: The Wind Sonic comes with an Aeroqual supplied cable and therefore the latest wire
outputs will be sent with the cable.
1.6. Particle Monitor
The particle monitor is an optional device that can be installed in the AQM 65 to provide reliable real
time indicative particulate measurement of TSP, PM10, PM2.5 or PM1 using a well proven near forward
light scattering nephelometer and high precision sharp cut cyclone.
1.6.1. Nephelometer
Aeroqual uses a customised nephelometer optical sensor from Met One Instruments. The optical sensor
uses light scattering from particulate matter to provide a continuous real-time measurement of airborne
particle mass. The light source is a visible laser diode and scattered light is measured in the near
forward angle using a focusing optics and a photo diode.
The sensor has an on-board temperature sensor which is corrected for thermal drift, sheath air filter to
keep the optics clean, automatic baseline drift correction and a fibre optic span system to provide a
check of the optical components.
The electrical connections to the nephelometer are summarised below:

White
Signal out (0-5 V)
Black/white

Yellow
Laser current monitor ( 10mV = 1 mA laser current)
Grey

1.6.2. Inlet heater
The nephelometer 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 nephelometer optics in high RH conditions.
1.6.3. Inbuilt filters
The nephelometer contains two filters which should be replaced at specified intervals. The “Sample”
filter is a coarse filter designed to protect the sample pump from excessive particle build-up. The
“Purge” filter is a fine filter which filters the sheath air flow and also produces particle-free air during the
auto-zero cycle. See Section 8.4.8 for information on changing the filters.
Safety: This sensor is considered a Class I laser product. Class I laser products are not
considered to be hazardous. There are no user serviceable parts inside the cover of the
sensor. The device contains a laser operating at 670 nm which is visible to the eye and can
cause damage to the eye if directly exposed. Only trained service personnel should
attempt servicing or repair of the sensor.

1.7. Profiler
1.7.1. Optical Particle Counter
Aeroqual uses a customised 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 60osolid 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.
1.7.2. 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. The optical unit 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.
1.7.3. Data Outputs
The Profiler can be configured to display and log the measurements detailed in the table below. The
sensor name is that used in the active sensors list and module settings.

RS485 Bus
The two wire RS485 bus connections are made using 20 cm CAT5 cables between the sensor modules
12 VDC Power Bus
All modules inside the AQM 65 operate from the 12VDC power. The power is supplied by a daisy chain
of black and red cables. To turn off the 12VDC power to the upper cabinet release the fuse holder.
Status LED
Each module includes a status LED which indicates that the electrical status of the module is
functioning correctly. It does not indicate the calibration status of the module.
a) Continuous on indicates correct electrical functionality
b) Slow flash (1 second) indicates warm up period
c) Fast flash (0.2 seconds) sensor failure
d) LED not on indicates no power to module.
e) The System Manager LED is a special case. This flashes to indicate RS485 bus traffic.
1.10. Pneumatic Connections
The sample gas passes into a PFA manifold behind the left hand side wall and is distributed to the
sensors. The gas modules sample via a single pump located in the bottom left of the enclosure. The
pump is easily accessible for maintenance. The sample inlet tubing is PFA 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 8.3.3.for
expected flow rates.
2. Set Up
The purpose of this section is to enable the user to correctly assemble, configure and commission their

2.2.2. Connect Inlet System
Once the AQM 65 has been wired the inlet
system needs to be connected before the
instrument is turned on. The inlet system consists
of an inert fluoropolymer and glass inlet with
mesh fitting which is designed to prevent
unwanted materials, such as water and dust,
being drawn into the instrument. The inlet pipe is
connected to the top of the AQM 65.
A 5/8 spanner is required to securely tighten the
¼” stainless steel compression fitting.
If an external filter holder has been purchased with the AQM 65, remove the mesh fitting from the inlet
pipe and screw the filter holder into place. The arrow on the filter holder should be pointing upwards.
2.2.3. Assembly of heated inlet for PM/Profiler (Optional)
If the AQM 65 is configured with a Nephelometer or Profiler the heated inlet needs to be connected prior
to the instrument being turned on.

iv. Connect power to Inlet Tube/Heater inside the enclosure
2.2.4. Connect third party sensors (Optional)
Third party sensors such as the Vaisala Weather Transmitter WXT520 or Met One MSO are connected
to the unit via the external glands located on the right hand side of the enclosure. Feed the cable
through the glands and connect to the auxiliary module using the instructions in Section 1.5.
Note: Turn off the AQM 65 before plugging in any external third part sensor.
2.3. Connect to the AQM 65

2.3.1. Initial Connection via Access Point Mode
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 AQM via the AQM 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 AQM 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 AQM. There
will be no internet connection on the user device when using this option. To connect you will need to
select the AQM WIFI network and enter the password.
Note: The default password will be “Aeroqual”.
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.
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 techn[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.
Note 2: See Section 3 for more connection options
