| Definition | The instrument's primary operating mechanism is the radiometric microbalance system, which relies on changes in the strength of a beta ray beam passing through the filter paper to determine changes in particulate mass collected. A Beta Attenuation Monitor is comprised of three main components: the PM air inlet, the central instrument, and the vacuum pump. |
