In order to fully understand the reasons for monitoring PM2.5 it’s important to address what PM2.5 is, and how it’s formed.

After all there is a saying “you cannot manage what you cannot measure”.

As opposed to its larger counterpart PM10 which is mainly formed from construction site activities and car tyre usage, PM2.5 is associated with fuel burning, industrial combustion processes and vehicle emissions. Because these day-to-day activities result in the majority of PM2.5 emissions, it makes this pollutant a global issue.

The monitoring of PM2.5 concentration is vital because it serves as the basis of pollution abatement strategies, providing important insights and relevant information that helps to define the pollution problem and aids solution planning.

ET’s range of monitors for the measurement of PM2.5.

ET can offer a wide range of solutions from Indicative sensors through to one of the successful air monitoring platforms in the world, the BAM-1020, which comes with DEFRA MCERTS approval.
