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. -
Page 12: Profiler
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 60 solid angle elliptical mirror at right angles to the laser beam. -
Page 13: Particle Mass Pump Modules

WiFi network extends out to where the AQM is installed. Alternatively the AQM 65 can be connected to the local network via an Ethernet cable from the AQM to the local router using the Ethernet output on the side of the AQM. -
Page 23: Cellular Network Connection
If the local network allows outside access (e.g. via VPN), connection to the AQM 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 AQM using Aeroqual Cloud through the internet because most local networks permit internet access. - Page 24 (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 AQM.

Page 41: Gas Cylinder Housing
Calibration can be configured to run at a set time for a chosen running period. See Section 4.3.2. for information on setting up the run scheduler in Aeroqual Connect/Cloud. The gain and offset parameters can then be adjusted as described in Section 6.1. and 6.2. -
Page 42: Calibration Standards And Equipment
The size of gas cylinder must also be considered. The gases required for performing a calibration using the direct method are different from those needed to perform a calibration using the dilution method. Aeroqual does not recommend direct delivery of calibration gas standards. Dilution Method Calibration gas is purchased at high concentrations and is then diluted to the appropriate span concentrations. -
Page 43: Gas Regulators
The three images below demonstrate a small portable gas cylinder (size 58L) from CalGaz, and a large and medium size cylinder from AirLiquide. All sizes are suitable for use with the Aeroqual Aircal1000 and AQM, the decision as to which size is best to use is based upon the considerations discussed above. -
