Particulate monitoring

MetOne Instruments has announced that the BAM-1020 Beta-Attenuation Mass Monitor has been approved under Australian Standard AS/NZS 3580.9.11.2008 for the determination of particulate matter, PM10, using Beta attenuation.

The BAM-1020 is currently claimed to be the only instrument available that has both Australian certification for PM10 and US EPA certification for PM10 and PM2.5.

Met One Instruments has been awarded US EPA Class III equivalency designation for a continuous PM2.5 particulate monitor.

Advantages of using the BAM-1020 real-time PM10 or PM2.5 for particulate/dust monitoring include a lower carbon footprint (75% energy saving compared to TEOM 1400A/B); fewer visits to the monitoring site to change collection media; only one flow channel reduces instrument calibration time; automatic span and zero checks every hour; no negative data due to particulate loading on filter media; minimises volatile losses due to use of new filter media every hour; and safety — the BAM 1020 uses a safe beta emitter source (C-14) which is a naturally occurring radio isotope.
