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.
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 ideal applications of this technology include:
