Spirant BAM

Particulate monitor

The Spirant™ BAM automatically measures and records airborne particulate concentrations using the beta ray attenuation method. It is designated by the US EPA as Federal Equivalent Method for PM10 and PM2.5 monitoring. The instrument also contains a comprehensive self-test function which allows the unit to test itself for any mechanical failures in the tape control system.

Beta ray attenuation

The Spirant BAM uses the beta ray attenuation method to measure particulate concentration. It performs continuous user selected evaluation of a variety of criteria for data validation including flow statistics and a comprehensive set of error codes such as power, flow, hardware, tape, nozzle, beta count and span check errors. Designed to run continuously with only monthly or bi-monthly scheduled maintenance – a single roll of filter tape will last for more than 60 days. Measurement data, configuration files, error logs, and flow statistics are stored in its internal data logger and are available via RS232 using common terminal programs and Airodis™ software.

Ease of operations

Designed to run continuously with only monthly or bi-monthly scheduled maintenance – a single roll of filter tape will last for more than 60 days. The instrument also contains a comprehensive self-test function which allows the unit to test itself for any mechanical failures in the tape control system.

Spirant BAM also comes with multiple options:
