The Met One Instruments Model BAM1020 has longstanding U.S. EPA designation as a Federal Equivalent Method (FEM) for continuous PM10 particulate monitoring. In addition, the BAM1020 is the world’s first instrument to obtain U.S. EPA FEM designation for continuous PM2.5 monitoring, when configured with the specified settings and accessories. The BAM1020 Continuous Particulate Monitor has also obtained corresponding certifications in other countries and regions.

The BAM1020 Continuous Particulate Monitor automatically measures and records airborne particulate concentration levels (in milligrams or micrograms per cubic meter) using the industry-proven principle of beta ray attenuation. Thousands of BAM1020 Continuous Particulate Monitor units are currently deployed worldwide, making the unit one of the most successful air monitoring platforms in the world.
