US EPA Approved for PM2.5 Class III FEM Ref (EQPM-1013-209)

 Flow Rate 16.7 l/m

 BAM 1022, Real-Time Portable Beta Attenuation Mass Monitor, continuously measures the mass concentration of ambient particulate matter collected onto glass filter tape with time resolution of one-minute.

The BAM 1022 employs an in-line sampling geometry in which the attenuation of beta rays across filter media is measured and particulate matter is sampled simultaneously. This allows ambient sampling to occur for virtually 60 minutes each hour. It also allows for beta ray measurements to be made for virtually the entire hour thereby improving sensitivity and time resolution.

Power consumption is modest as no air conditioning is required. No component weighs more than 40 lb. (18K) meaning that it is easily transportable by one person. The entire system may be set up and put into operation in less than ten minutes.

The BAM 1022 offers the following advanced features:
• In-Situ measurement of PM that provides high accuracy, minimal measurement artifacts.
• Reduced background determination frequency.
• Unsurpassed performance under high ambient dew point operation.
• Advanced communications features allowing remote operation and cloud-based communication.
• Advanced diagnostics.
• Improved sensitivity compared to other in-line beta attenuation mass monitors.
• Meteorological and other sensor inputs.
