Our customers in the research and consulting community want quick and accurate air quality data from a compact instrument that can be used on multiple projects. They are less constrained by the need to have US EPA-type conformity, provided the data is robust and traceable back to reference methods.
Sensor-based equipment opens up new opportunities
Our instruments use sensors rather than analyzers, which gives two big advantages: 1) parameters can be measured and logged every minute, and 2) sensors are cheaper than analyzers, enabling more instruments in the field. Air quality data with increased spatial and temporal resolution can open up new areas for research and consulting, such as in mapping urban hotspots, personal exposure monitoring, or wide area sensor networks.
Configurable and cost effective equipment that makes your budget go further
Because our products are highly configurable we can match the parameters to the needs of your project. Plus, later on, you can add modules to measure parameters that weren’t initially needed. The relative affordability of the instruments means you can free up budget for other non-equipment related expenses.
Air quality monitoring equipment that is well suited for the purposes of education
Current sophisticated, expensive ambient air pollution monitoring technology is not economically sustainable as the sole approach and cannot keep up with current needs, specifically new monitoring networks and special purpose monitoring.US EPA: New Generation Air Monitoring Roadmap 2013
Environmental Impact Assessments (EIA)
Consultants are always looking for data to substantiate the modelling upon which their advice depends. But client budgets rarely extend far enough to allow for the duration and type of air monitoring required. In a competitive market consultants have no choice but to look for alternatives, provided they can be shown to represent the best available method.
Best available method might often be a monitoring solution that is real-time, or a monitor that is able to be located in a tight spot, or a monitor that can be quickly deployed and relocated as required. Increasingly consultants are looking beyond US EPA-type analyzers and seeking flexible, more portable, more affordable instruments. At the same time those instruments must produce robust data that can be traced back to reference methods.
Aeroqual has developed a range of instruments ideal for short to mid term monitoring assignments. The AQM 60 in particular offers the best balance of performance, portability, and price that makes it extremely attractive for EIAs and is increasingly seen as best available method for a wide range of projects.
Low cost sensor networks are an exciting idea with great potential. So far the potential is limited by issues with performance, practical support of sensors in the field, and knowledge about how best to apply low cost sensors for the advancement of air quality understanding. For these reasons low cost sensor networks have not yet graduated from isolated projects to being a real world proposition. Many low cost sensor makers are reluctant to share data with the wider community.
Aeroqual has been involved in a number of low cost sensor network projects and continues to invest in applied research, often in partnership with others. For example, the case study to the right features the ozone sensor network we deployed with Sonoma Technology Inc (STI) who are leading air quality scientists and consultants based in the United States. The project uniquely demonstrated the value of increased measurement density across a wide area.
Because of our leading position in sensor-based instruments we were highlighted in the US EPA’s Air Sensor Guidebook for low cost sensors – ozone, carbon monoxide, and nitrogen dioxide in particular. If you haven’t already read it we recommend it as a great introduction to the field and a must-read for anyone looking to invest in the equipment needed to make or deploy a low cost sensor network.
