AEROQUAL 500 series

The Series 500 air quality sensor enables accurate real-time surveying of common outdoor air pollutants, all in an ultra portable handheld monitor. Air quality professionals typically use the Series 500 for short term air quality studies and carrying out checks on pollution “hot spots”. The Series 500 can also be deployed for short term fixed monitoring by adding an optional outdoor enclosure. Other features on the Series 500 include monitor ID and location ID. Monitor ID identifies the monitor uniquely and ensures that all data from it are tied to that monitor. Location ID can be used to tag measurements to a specific location which is helpful when sampling at a number of sites over the course of a day or week.


The DustMate is highly effective for checking air quality within buildings. It has one second time resolution which also allows it to be used as a road-side indicator to identify high pollution vehicles as they pass. The instrument will continuously indicate the concentration of thoracic, inhalable and respirable particles down to 0.1 micrograms per cubic metre. It will indicate TSP, PM10, PM2.5 and PM1 concentrations, in its environmental mode.

Osiris (Particulate Monitoring)

The Osiris is a small and compact instrument that can be used to study short to long term particulate monitoring. Powered by various power options to suit your application. The Osiris can be used effectively to determine exceedance areas. All instruments feature internal data logging for the particle concentrations. Osiris also allow wind speed and direction, temperature, humidity, rainfall and two external gas or noise meter inputs to be recorded at the same time.
