Particulate matter, known as PM10 and PM2.5, are of great concern as the particles are small enough to enter the lungs causing respiratory and other health problems. These two class sizes are the normal sampling standards measured throughout the world.

Air quality Monitors Ltd has over 40 years combined knowledge in particulate matter monitoring. AQM offers a range of particulate monitors with a variety of techniques including light scatter and beta attenuation for compliance monitoring. If you operate a quarry or mineral extraction site, a waste management facility, a demolition/construction site, a landfill site or are a local authority requiring equipment to monitor particulate matter including TSP, PM10, PM2.5 and PM1 we can provide a service for you. Our monitors can be incorporated into air conditioned weatherproof shelters or alternatively can be used as stand alone units.

We have instruments for sale and hire.

Protinus 1000

Protinus 1000

The Protinus 1000 is a particulate monitor which boasts accurate, real-time particle monitoring, with multiple parameters measuring TSP, PM10 or PM2.5. They are ideally suited for use around mines, quarries, construction and other dust generating activities.

This instrument uses the forward light scatter method which, when correlated against the monitor’s gravimetric sample filter, provides accurate and instantaneous measurement of dust concentrations. The Protinus 1000 also incorporates an inbuilt sample heater which is controlled by a relative humidity sensor, to ensure accurate measurements are not influenced by excess ambient moisture.

The Gravimetric Sampling Filter method samples dust onto an internal 47mm filter. This filter can also be used for later chemical analysis such as XRF to determine heavy metal concentrations.
