Lear Siegler Australasia  specialises in the supply of a comprehensive range of air quality monitoring instruments.

In addition to manufacturing these instruments, the company also sources equipment from world-leading companies.

Air quality monitoring instruments from Lear Siegler are designed for monitoring particulate matter or gaseous pollution in ambient air, and include reference instruments for sample collection through to real-time online measurement instruments.

Air pollution is a major environmental issue in Australia as it impacts the quality of life, the health of the community and the sustainability of lifestyles. Air pollution is caused by motor vehicles, solid fuel combustion, industrial emissions and materials such as paints and adhesives in new buildings.

Lear Siegler’s air quality monitoring instruments can be used to measure particulate matter in ambient air employing one of two methods: using a reference instrument or real-time online measurement.

Reference instruments take a defined sample of particulate matter in the ambient air, which is then analysed in the lab.

Real-time online measurement is a continuous measurement process, which is dated and time stamped and can be done by any of the following methods based on application and size of particulate matter:

  • Beta gauge (radioactive absorption)
  • Tapered element oscillating microbalance
  • Light scattering
  • Combination of light scattering and beta gauge
Several technologies are available for measuring different gases in the ambient air, which include:
  • Non-Dispersive Infrared (NDIR)
  • Fourier (FTIR)
  • Chemiluminescent
  • Pulsed fluorescence
  • UV absorption
  • Flame Ionisation Detector
  • Paramagnetic
  • Electrochemical
