BAM-1022 Beta 衰减质量监测器

Met One Instruments, Inc. BAM 1022 实时便携式 Beta 衰减质量监控器以一分钟的时间分辨率连续测量收集到玻璃滤带上的环境颗粒物的质量浓度。BAM 1022 采用在线采样几何结构，其中测量 β 射线穿过过滤介质的衰减，同时对颗粒物质进行采样。这允许每小时进行近 60 分钟的环境采样。它还允许在几乎整个小时内进行 β 射线测量，从而提高灵敏度和时间分辨率。

BAM 1022 采用独特的“原位”采样技术，其中 β 测量值保持在高于环境条件的几乎固定温度，从而**限度地减少由于半挥发性颗粒材料损失或样品流中水分过多而导致的测量误差。无需使用昂贵的 Nafion 干燥器即可进行高精度测量，从而提高可靠性并降低运营成本。综合避难所不使用空调，采样系统也不使用分流器。这导致更容易的服务、增强的可靠性和更低的功耗。

BAM 1022 集成到其自己的轻型设备防护罩中，带有一个易于拆卸的泵箱，非常适合安装在没有永久性结构或步入式防护罩的区域。由于不需要空调，因此功耗适中。没有一个组件的重量超过 40 磅，这意味着它可以由一个人轻松搬运。整个系统可以在不到十分钟的时间内完成设置并投入运行。

BAM-1022 Beta Attenuation Mass 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 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.

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.

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.
