Particulate Matter Monitoring Instruments
DEC uses filter‐based instruments to measure particulate pollution. These instruments draw air at a specified rate through a filter. The amount of particle matter that becomes trapped on the filter is measured in different ways depending on the type of instrument. Some instruments, such as the HiVol and the Partisol, require that filters be weighed in a lab. Others, such as the BAM, eBAM, and TEOM, measure the particulate collected on the filter directly. Below are photos of some of these instruments.
