BAM stands for Beta Attenuation Monitor, the BAM-1020 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 BAM-1020 units are currently deployed worldwide, making the unit one of the most successful air monitoring platforms in the world.

​

The Met One Instruments Model BAM-1020 was the first instrument to obtain U.S. EPA Federal Equivalent Method (FEM) designation for continuous PM2.5 monitoring, in addition to its longstanding EPA designation for PM10 monitoring. The BAM-1020 has also obtained the corresponding PM2.5 and PM10 certifications in the European Union. Two BAM-1020 units can also be operated together as an EPA designated PM10-2.5 coarse method. Met One Instruments supplies complete sampling accessory kits for compliance with each designation.

Data Collection

All data files are accessible via an industry standard duplex RS-232 serial port using common terminal programs or Met One Instruments, Inc. software such as AirPlus®. The data is available in a variety of formats. Configuration files, error logs, and flow statistics are also available. Ethernet and USB data collection are standard.

The BAM 1020 is also fully compatible with our COMET Cloud service for cloud-based data collection, data display/monitoring and data storage.

​

Error Handling

The BAM 1020 performs continuous evaluation of numerous criteria for data validation. These include flow statistics and a comprehensive set of error codes including power failures, flow failures, hardware failures, tape errors, nozzle errors, span check errors, beta count errors, and more.

 

Maintenance

The BAM 1020 is designed to run continuously for up to 60 days between site visits and maintenance. The BAM 1020 also contains a comprehensive self-test function which allows the unit to routinely test itself for any mechanical failures in the tape control system.
