Appendix 5 AQM 65 site installation and commissioning with
mounting examples
Commissioning is the process of setting up a new instrument to work correctly on site. It is important
that the correct procedure for commissioning AQM 65 instruments is followed to ensure reliable
instrument operation and to meet or exceed your data quality objectives. All AQM 65 instruments are
supplied with a traceable factory calibration. This calibration is applicable to the commissioning phase
and accordingly Aeroqual does not recommend an initial calibration as part of instrument
commissioning.
NOTE
: Aeroqual recommends that instruments are installed and commissioned, and allowed to run
with the factory calibration for the first month. Based on this first month of data, an assessment
of the installation can be made and a calibration schedule then developed for the instrument
and the site.
A commissioning report template (.pdf) is available from the training website:

Visit potential site and assess instrument location and suitability
Before the instrument arrives ensure that the site will be representative of the pollutants you intend to
measure, be secure but with adequate access, and be appropriately open to all wind directions. If you
are planning a permanent deployment, check that there is nothing nearby which could change and
affect your project
– like trees, planned buildings or new roads and other potential interferences.
Both Mains and Solar power can be used, but these will need to be available and installed before the
instrument arrives When installing power outlets (110 VAC to 230 VAC) for the AQM 65, they should
be weatherproof and installed safely. Install 2 power outlets, 1 for the AQM 65 and one for calibration
equipment.
Install the AQM 65 on site
See Appendix 2 for AQM 65 dimensions and weight.
Most sites will require a way of securely mounting the AQM 65. Pole
Brackets (89 mm / 3 ½ “304
Stainless U-Bolt) are included to mount the instrument on a pole, anchored to the ground. (
Figure 3
)
Small platforms have also been used successfully too (
Figure 1
). If you have ordered Auxiliary sensors
(Weather, noise etc.) you will need to provide a means of mounting these also.
Figure 1
Shows an AQM 65 mounted on a steel stand with an extended pole. The AQM 65 is secured
to the pole using the pole mounting brackets and the wind sensor is mounted to the top of the pole.
Figure 2
shows the temperature and humidity sensor on the bottom plate of the AQM and the
compressor cooling fan on the back plate, these must have sufficient air flow around them to function
correctly.
Figure 3
Shows an AQM 65 mounted to a pole, an additional power socket is included to allow a laptop
or external calibrator to be plugged in.
Figure 4
Shows a stand with a flat base, and an AQM installation which blocks the fan at the back.
These situations must be avoided.
