BAM 1022

Beta Attenuation Mass Monitor

The BAM 1022 Real-Time Portable Beta Attenuation Mass Monitor from Met One Instruments Powered by Acoem continuously measures the mass concentration of ambient particulate matter collected onto filter tape with a 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.

Efficient and Accurate BAM 1022 Sampling

The BAM 1022 employs a unique “in-situ” sampling technique where the beta measurement is kept at a nearly fixed temperature above ambient conditions, thereby minimizing measurement error due to loss of semi-volatile particulate material or excessive moisture in the sample stream. Highly accurate measurements are made without having to employ expensive Nafion dryers, thereby increasing reliability and decreasing operating costs. The integrated shelter does not employ air conditioning, nor does the sampling system employ flow splitters. This results in easier service, enhanced reliability, and lower power consumption.

Portable and Reliable BAM-1022 System

The BAM-1022 comes integrated into its own lightweight equipment shelter with an easily detachable pump box making it ideal for installation in areas where no permanent structure or walk-in shelter is available. Power consumption is modest as no air conditioning is required. No component weighs more than 40 lb. 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.
