TECHNOLOGY OVERVIEW

A New Zealand company has developed a low-cost and portable system to provide continuous, real-time air quality measurement and monitoring for outdoor airborne particulates. The system developed is ideal for a wide variety of applications where the continuous real-time monitoring of airborne particulates such as dust is required. Paired with a datalogger, communications and Global Positioning System, the solution allows remote monitoring of the environment, with data streamed to desktops, alarm systems or interpretative layers. The company is seeking partnerships for co-development or for commercial agreements with technical assistance.

TECHNOLOGY FEATURES & SPECIFICATIONS

With a low detection limit, high accuracy and high resolution, the portable measurement device developed by this company utilises near-forward light scattering sensors with a sensitivity of 1 μg/m3 and a particle size sensitivity range of 0.1-100 micron, capable of measuring TSP, PM10, PM2.5 and PM1.0. It features a sample period of 1 second and a sample flow rate of 2 litres per minute, making it a cost-effective solution for long-term and unattended operations to monitor outdoor airborne particulates and air quality.

POTENTIAL APPLICATIONS

Potential ideal applications of this technology include:

  • Monitoring spatial variation within an airshed
  • Comparing particulate concentration in different geographic areas
  • Cost effective fence-line monitoring
  • Emergency smoke or dust monitoring
  • Short-term research project
  • Indicative PM10 or PM2.5 monitoring
  • Distributed spatial network operation
  • Intermediate layer monitoring devices within a hierarchical network
  • Mobile sensor monitoring for comparative assessment of multiple airsheds
  • Cost-effective tool for comparing potential monitoring sites

Benefits

Benefits of this solution to monitor outdoor airborne particulates include:

  • Long-term unattended operation
  • Low detection limit, high accuracy and resolution
  • Real-time online access to instrumental data
  • Ability to set alarms (SMS, email) when limits are reached
  • Automatically records position for extra mobility and relocation as needed
  • Cost-effective rental for short-term projects
  • Solar powered or mains powered
  • Non-stepwise, continuous monitoring
  • Utilising near-forward light scattering
