Aeroqual PM Sensor Head 2.5 and 10 (PM)

This Particulate (PM) Sensor head simultaneously measures PM10 and PM2.5 from 0.001 to 1.000 mg/m3 with a 0.001 mg/3 resolution and +/- (0.005 mg/m3 + 15% of reading) accuracy.

Particulate Matter Information

5 In Stock

This Particulate Matter (PM) sensor head uses laser and optical counter 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 PM2.5 and PM10.  This sensor will measure PM from 0.001-1.000 mg/m3 with an accuracy being +/- (0.005 mg/m3 + 15% of reading).  The unit has a response time of 5 seconds.


This sensor head will be a direct fit onto any Series-200, Series-300, or Series-500 Aeroqual ozone monitor.  This head can be purchased as an addition to your existing monitor, or with a new base unit.  To purchase with a base unit see our Aeroqual ozone monitor page.  If you currently have an Aeroqual ozone monitor this sensor will be a direct fit for your current monitor.  The Series-200, Series-300, or Series-500 will automatically detect this as a Particulate Matter (PM) head and react accordingly.

HOw does it work?

Active sampling and humidity compensation

Like all Aeroqual sensor heads the PM sensor head has an in-built fan to ensure a stable and precise flow of sample air to the sensor. The sensor head also compensates for humidity by way of an on-board humidity sensor. In humid conditions light scattering sensors are likely to read high because moisture surrounds particles, causing them to appear ‘bigger’. The humidity compensation feature reduces this effect on the measurement.

Display and K factor application

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 micrograms per cubic meter (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.

Battery and datalogging

The Series 200/300/500 monitors come with a long-life Lithium battery. When using the PM sensor head the battery allows for 24 hours of remote operation between charges. Recharging takes just 3 hours. The monitor can be plugged into the mains and left to run indefinitely. Finally, 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.
