連續(xù)顆粒物監(jiān)測儀 BAM 1020

BAM 1020 使用經(jīng)過行業(yè)驗證的 β 射線衰減原理自動測量和記錄空氣中的顆粒物濃度水平（以毫克或微克每立方米為單位）。目前全球部署了數(shù)千臺 BAM 1020 裝置，使該裝置成為世界上**成功的空氣監(jiān)測平臺之一。

Met One Instruments 的 BAM 1020 型是**個獲得美國 EPA 聯(lián)邦等效方法 (FEM) 連續(xù) PM 2.5監(jiān)測指定的儀器，此外，它還長期獲得 EPA 監(jiān)測 PM 10的指定。BAM 1020還獲得了歐盟相應的PM 2.5和PM 10認證。兩個 BAM 1020 裝置也可以作為 EPA 指定的 PM 10 – 2.5粗略方法一起運行。Met One Instruments 提供完整的采樣附件套件，以符合每個指定。

連續(xù)顆粒物監(jiān)測儀 BAM 1020 操作/界面

在每個采樣小時開始時，一個小型14 C（碳 14）源通過一塊干凈的濾帶發(fā)射出恒定的高能電子源（稱為 β 射線）。這些 β 射線由靈敏的閃爍檢測器檢測和計數(shù)，以確定零讀數(shù)。然后，BAM 1020 將這一帶點推進到樣品噴嘴，真空泵將測量和控制量的外部空氣拉過過濾帶，并在其上裝載環(huán)境灰塵。在采樣時間結(jié)束時，該塵點被放回到 β 源和檢測器之間，從而導致用于確定濾帶上顆粒物質(zhì)量的 β 射線信號衰減。該質(zhì)量用于計算環(huán)境空氣中顆粒物的體積濃度。

Continuous Particulate Monitor BAM 1020

The BAM 1020 automatically measures and records airborne particulate concentration levels (in milligrams or micrograms per cubic meter) using the industry-proven principle of beta ray attenuation. Thousands of BAM 1020 units are currently deployed worldwide, making the unit one of the most successful air monitoring platforms in the world.
 

DESIGNATIONS

Met One Instruments’ Model BAM 1020 was the first instrument to obtain U.S. EPA Federal Equivalent Method (FEM) designation for continuous PM2.5 monitoring, in addition to its longstanding EPA designation for PM10 monitoring. The BAM 1020 has also obtained the corresponding PM2.5 and PM10 certifications in the European Union. Two BAM 1020 units can also be operated together as an EPA designated PM10–2.5 coarse method. Met One Instruments supplies complete sampling accessory kits for compliance with each designation.

OPERATIONS / INTERFACE

At the beginning of each sample hour, a small 14C (carbon-14) source emits a constant source of high-energy electrons (known as beta rays) through a spot of clean filter tape. These beta rays are detected and counted by a sensitive scintillation detector to determine a zero reading. The BAM 1020 then advances this spot of tape to the sample nozzle, where a vacuum pump pulls a measured and controlled amount of outside air through the filter tape, loading it with ambient dust. At the end of the sample hour, this dust spot is placed back between the beta source and the detector, thereby causing attenuation of the beta ray signal which is used to determine the mass of the particulate matter on the filter tape. This mass is used to calculate the volumetric concentration of particulate matter in ambient air.

DATA COLLECTION

All data files are accessible via an industry standard duplex RS-232 serial port using common terminal programs or Met One Instruments’ software such as Air Plus® or Comet®. The data is available in a variety of formats including daily reports, last record, all data, and new records since last download. Configuration files, error logs, and flow statistics are also available. Ethernet and USB data collection are standard.
