1. OVERVIEW
The AirMetER-DX is a remote area dust monitor for the simultaneous detection and measurement of particulate
matter PM2.5 and PM10 size fractions.
Housed in a weatherproof IP66 rated polycarbonate enclosure, the AirMetER-DX is ideal for continuous round
the clock outdoor monitoring and has data logging capacity at a minimum of 365 days at one-minute intervals. It
has a built-in log and forward capability to capture one week of operation in the event of a network disruption.
An aluminium heated inlet with TSP head minimises the detrimental effect of humidity on the accuracy of dust
measurement.
Integrating seamlessly with the LiveSense cloud portal for remote data access, this secure data portal enables
users to access monitoring logs, set customisable alerts, manage monitoring reports and more. The web-service
application is accessible on both desktop PC and mobile smart devices.
The AirMetER-DX should be powered on 12VDC and is available with an optional Bluetooth enabled solar-power
system that can provide up to 5 days autonomous operation.
For mains powered applications, an IP67 rated, 240VAC to 12VDC, 5A power supply is available.

4. INSTALLATION
Use of the AirMetER-DX monitor in applications contrary to the conditions of
use criteria may present a safety risk and/or void any instrument warranty.
CONDITIONS OF USE
The AirMetER-DX is:
i. NOT certified for use in hazardous area classified zones.
ii. NOT designed for ensuring safety of personnel and equipment.
The AirMetER-DX is supplied with brackets pre-fitted to support standard pipe-clamp pole mount inserts suitable
for installation on standard masts or poles ranging from 40-105mm in diameter. An adjustable spanner or flat-
blade screwdriver may be utilised to either tighten or release the pipe clamp to suit the intended structure
diameter. Care should be taken during installation to ensure the AirMetER-DX is level and firmly secured.

FILTER EXHANGE
The AirMetER-DX contains up to two filters:
9933-05-CQ –Dust filter
121-5866 –Pneumatic silencer
The pneumatic silencer is installed on AirMetER-DX instruments manufactured before February 2023. This only
requires replacement when polluted or damaged. It is recommended that the dust filter be exchanged no less
than annually. The filters should be monitored and inspected at regular intervals in new applications to gain an
insight into how long the filters last before discolouration.
It should be noted that the frequency of filter exchanges may be affected by the
application and location of the device.
The dust filter is secured to the tubing with push fittings. Compress the push fitting to release the filter from the
fitting. Ensure when installing the new filter to properly click the filter in place into both push fittings, keeping the
directional arrow pointing towards the pump.
After completing the pump filter exchange, it is important to again validate the inlet flowrate to ensure no leaks
have been created during this process. The inlet flowrate is set to 2L/m ±5%, as detailed in the flowrate
calibration section below (PAGE 14).
The pneumatic silencer can be removed by unscrewing it anti-clockwise before replacing it with the new silencer.
Take care to ensure the O-ring does not fall off the new silencer when replacing.

TSP HEAD CLEANING
A TSP head should be installed on all heated inlets at factory and while installed in
the field, these need to be periodically cleaned. The time interval between
cleaning varies depending on the application and location of the device. It is
recommended to clean and check for any blockages within the TSP head and
heated inlet assembly during annual routine maintenance.
Some instruments will have a PM10 sharp cut cyclone (AE10-2) installed instead of
the standard TSP head. These are used in applications where high levels of
particulates larger than PM10 are found and need to be filtered out as to not
damage the sensor. When the sharp cut cyclone is being used, it needs to be
monitored and cleaned at a much higher frequency.
This process may be completed using a brush and compressed air if available.
FLOW RATE CALIBRATION
Attach a 0.4-5L/m rotameter (320-4A5) to the inlet of the AirMetER-DX. The flowmeter should indicate 2L/m
±5%. Should this be out of tolerance, check to ensure there are no leaks and that there is pressure when blocking
the heated inlet. Manual adjustment of the pump flow meter may be completed to achieve this as depicted
below.
Unscrew 4x PH screws from the AirMetER AX-P top case (NOTE: these screws are retaining).
Figure 6.5 –Pump Top
Figure 6.6 –Pump Internal
Figure 6.7 –Pump Control Internal
Using a small flat-blade driver, remove the lid from the control box within the pump module.
Adjust the potentiometer clockwise to increase the flowrate and anti-clockwise to decrease the flowrate in order
to achieve 2L/m ± 5%.
In the event the flowrate cannot maintain 2L/m ± 5% at the inlet, losses can be diagnosed through-out the flow
path: Heated inlet > particulate sensor module > dust filter > pump module > external exhaust

7. FIELD K FACTOR ADJUSTMENT
Field calibration (K Factor Adjustment) of the AirMetER-DX is an important process to ensure data accuracy with
respect to the location of the instrument. Field calibration should not be considered a substitute for factory
calibration.
In order to perform a K Factor adjustment, a gravimetric sample must be collected relative to the newly installed
instrument.
NOTE: Ensure correct methods for conducting a gravimetric sample are followed to ensure an accurate K Factor
adjustment –If unsure regarding this process please contact Air-Met Scientific.
Provide collected data to Air-Met Scientific and a K Factor adjustment may be completed remotely.
