Measuring opacity and particulate matter
With cement production being a potential source of several hazardous air pollutants (HAPs) that are subject to strict regulations to protect human health and the wider environment, AMETEK Land talks technologies available for the monitoring of smoke and dust emissions from the process. By Derek Stuart, AMETEK Land, UK.

Among the most obvious of hazardous air pollutants (HAPs), as it is readily visible by eye, is particulate matter (PM) – particles of smoke and dust. Small particles below 2.5µm in diameter are a special concern as they pose the greatest risk to health.
