Total Suspended Particulate (TSP)
Pollutants - Particles - TSP


AirQuality Limited can offer a variety of monitoring options for the monitoring of TSP including:

  • Beta Attenuation Monitor
  • Dustmote optical particulate monitor
  • High Volume Sampler

More detail on each of these options is shown below:

Beta Attenuation Monitor

The AirQuality Limited BAM-mote continuously measures TSP, PM10, PM2.5 or PM1 using beta attenuation. The BAM-mote is a fully integrated package consisting of a Beta attenuation monitor coupled with an on-board modem, datalogger, data storage and Global Positioning System.

  •  Continuous, non-stepwise measurement
  •  Long term, unattended operation
  •  Designed to meet AS/NZS 3580.11 2008
  •  Capable of measuring TSP, PM10, PM2.5 or PM1
  •  Low detection limit, high accuracy and resolution
  •  Real time online access to instrumental data

Dustmote Optical Particulate Monitor

The AirQuality Limited Dustmote continuous optical particulate monitor uses near-forward light scattering technology in combination with a datalogger, communications and Global Positioning System.


Pricing is dependent upon:

  • The length of time you wish to monitor for
  • The type of equipment you wish to use
  • Whether you wish to purchase or rent the monitoring instrumentation
  • The level of data validation and reporting
  • Whether an instrument enclosure is required
  • Whether mains or solar powered options are required
  • Whether wind speed and direction also need to be measured

Our clients tell us that we offer very competitive quotes for both the supply and operation of these instruments.

Total suspended particulates (TSP) are solid matter or liquid droplets from smoke, dust, fuel ash, or condensing vapours that can be suspended in the air. They either come from natural sources such as the sea (wind-blown sea salt) and soil (wind-blown soil particles) or from man-made sources such as diesel exhausts, construction activities and factories. TSPs include a range of different sized particles. The coarser particles are 50-100 micrometres (where 100 micrometres is the thickness of a human hair) and finer particles are smaller than 10 micrometres in diameter.

They represent a broad class of chemical particles and may include inorganic fibres, trace metals (such as lead) and a variety of organic materials. TSP may originate from combustion, forming hydrocarbons, or from sulphates and nitrates formed during sulphur dioxide or nitrogen dioxide emissions.

Particulates can be inhaled but larger particulates can be filtered by the upper respiratory tract. Smaller particulates (respiratory suspended particulates) can enter deeper into the lungs.
