Met One BAM 1022
Ambient Air Monitor

The Met One Instruments, Inc. 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.

The BAM-1022 employs a unique “in-situ” sampling technique where the beta measurement is kept at a near fixed temperature above ambient conditions, thereby minimizing measurement error due to loss of semi-volatile particulate material or due to excessive moisture in the sample stream. The BAM-1022 comes integrated into its own lightweight equipment shelter with easily detachable pump box making it ideal for installation in areas where no permanent structure or walk-in shelter is available.

The BAM 1022 has US-EPA designation for PM 2.5 (EQPM-1013-209)
