PM10 / PM2.5 Portable Particulate Monitor

PM10 / PM2.5 Portable Particulate Monitor

The Aeroqual PM10 / PM2.5 Portable Particulate Monitor provides accurate and simultaneous real-time measurement of PM10 and PM2.5 in ambient outdoor and indoor environments. Measure gaseous pollutants by simply swapping the PM sensor head for the gas sensor head of your choice (gas sensor heads available separately). Suitable for use on a range of projects, including indoor / outdoor air quality testing, personal exposure monitoring, and short-term fixed monitoring.

Simultaneous measurement of particulate matter (PM10 & PM2.5) via a truly handheld monitor that fits comfortably in the hand

Measure up to 30 different gaseous pollutants with the addition of extra swappable gas sensors (CO, CO2, NO2, VOC, O3, SO2, H2S and more)

Long-life lithium battery allows for 24 hours of remote operation for every 3-hour charge

Product overview

The PM10 / PM2.5 Portable Particulate Monitor is a truly handheld portable monitor that measures PM10 and PM2.5 in real-time. Compatible with Aeroqual’s Series 200/300/500 air quality monitors, the PM sensor head uses a laser and optical sensor to measure light scattered from particles passing through the laser beam. The optical sensor transforms scattered light into electrical signals which are processed to provide mass measurements – in this case PM2.5 and PM10.

The PM sensor head is supplied factory-calibrated and ready to use. An electrical signal is passed from the sensor head to the Aeroqual Series 200/300/500 base unit which displays the measurements on the screen in milligrams per cubic metre (mg/m3). In the case of the Series 300 and 500 base units, a gain (or K factor) can be applied to the sensor output. This allows users to adjust the readings relative to a trusted source such as EPA-approved reference monitor.

In the Series 500 model, measurements can be stored on the device and downloaded later to a computer via the USB cable and bundled software. The Series 500 is also featured in our new Outdoor Air Quality Test Kit and Indoor Air Quality Test Kit, a convenient way to test multiple gases and particulates in the air around you.

What can it measure?

The PM10 / PM2.5 Portable Particulate Monitor measures PM10 and PM2.5 simultaneously, with the option of adding gaseous sensor heads to measure up to 16 different pollutants (CO, CO2, NO2, VOC, O3, SO2, H2S and more.)

This product includes:

  • PM sensor head

  • Monitor base

  • LCD digital display

  • Lithium battery and charger

  • In-built datalogger

  • Monitor to USB cable

  • PC software

FAQs

There are many different types of outdoor air pollution. Measuring them all would be too expensive, so regulators focus on a smaller group of common air pollutants, sometimes known as the criteria pollutants. The criteria pollutants are:

  • Nitrogen dioxide (NO2)

  • Sulfur dioxide (SO2)

  • Carbon monoxide (CO)

  • Ozone (O3)

  • Particulate matter (PM)

As always requirements should be confirmed with your local regulatory body.

Sensors are housed within an interchangeable ‘sensor head’ that attaches to the monitor base. You can choose from up to 28 different gas and particulate sensor heads. Each sensor head contains a single gas or particle sensor. Swapping sensor heads takes seconds and no configuration or re-calibration is required.

You can find our specifications for our sensor heads here:

Aeroqual-Portable-Fixed-Sensor-Specifications.pdf

Note: Accuracy may drift as the sensor ages.

Aeroqual recommends replacement after two years, however higher exposure levels or harsh environments can lead to a significant reduction in life expectancy. Your monitor display is likely to indicate Sensor Failure or Sensor Ageing if the sensor is nearing the end of its useful life.

Note: Sensor heads may degrade even when unused and in storage.

How many sensors can I use on the monitor at once?

You can only connect one gas or particulate sensor head at a time to monitor. However, you are able to connect the optional temperature and humidity sensor at the same time as a gas or particulate sensor head.

Can I use the PM sensor head with any portable monitor?

The PM sensor is compatible with Series 200/300/500 monitors with software version 6.4 introduced in November 2014.

What is the PPM to mg/m³ conversion factor?

PPM is an absolute measurement, whilst mg/m3 varies depending upon pressure and temperature. The portable monitor measures in PPM and applies a conversion factor if you wish to measure in mg/m3.

NH3 - 0.76, CO - 1.25, CO2 - 1.96, CL2 - 3.16, CH2O - 1.34, H2 - 0.082, CH4 - 0.72, H2S - 1.52, NO2 - 2.05, NMHC - 2.5, O3 - 2.14, C2CL4 - 6.78, SO2 - 2.86, VOC - 2.5, PM - N/A*

*as particulate matter varies in size, unlike a gas molecule, PPM is not a valid unit of measurement

Do I return the instrument for calibration?

Only the sensor head needs to be calibrated. The base unit does not need to be calibrated. All parameters are stored on the sensor head.

The sensor head calibration should be completed after the first year. Aeroqual does not recommend a second factory calibration, but rather replacement after two years of operation.

See a range of frequently asked questions on calibration here.

How long can I log data for (Series 500 only)?

The Series 500 handheld unit can store a limited number of data points (8188), meaning that the length of time that data can be logged depends upon the frequency and number of data points recorded. For example:

  • If you are logging every minute for one gas (i.e. one data point per minute) you can log for 8188 minutes.

  • If you are logging every minute for one gas, temperature and humidity (i.e. 3 data points per minute) you can log for 2729 minutes.

Decrease the logging frequency for the ability to log over a longer timeframe.

Note: Once capacity is reached new data will begin to overwrite the oldest logged data.

What communication options does the portable monitor have?

S200: None

S300: 0-5V Analog output (current reading only)

S500: 0-5V Analog output (current reading only), RS232 (current, logged data and instrument control) to PC software via USB adapter. RS232 protocol available upon request for third party software integration.

What is the “Control” function (Series 300 & 500 only)?

This is designed to control generation of a gas such as ozone from an ozone generator. The control pin can be wired to control a gas concentration between upper and lower concentration limits. The upper and lower limits can be set by the user via this control function.

Refer to the relevant section of the user guide for wiring instructions.

What accessories are available for the portable monitors?
