PM10/PM2.5 Particulate Monitor
Compatible with Aeroqual’s Series 200/300/500 air quality monitors, the portable particulate monitor will output particulate matter (PM) measurements for PM10 and PM2.5 in real-time.
The monitor can also be used to measure gaseous pollutants such as carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2), and hydrogen sulfide (H2S). Simply swap the PM sensor head for the gas sensor head of your choice.
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.
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.
