E-BAM 便携式环境 Beta 衰减质量监测器

Met One Instruments E-BAM 作为便携式实时 Beta 测量仪属于同类产品，可与美国 EPA 的 PM 2.5 和 PM 10颗粒物测量方法相媲美。E-BAM 旨在通过提供真正准确、精确、实时的细颗粒物测量来满足用户、监管机构以及健康和安全界人士的需求。此外，它坚固、便携、电池供电，可在 15 分钟内部署。

高级功能

准确度和精密度符合美国 EPA 对 III 类 PM 2.5 和 PM 10 测量的要求。

实时、准确的结果，无需校正因素——无论季节或地理位置如何。

环境采样可准确测量半挥发性硝酸盐和有机化合物。

轻巧、坚固的结构可在几分钟内轻松安装在三脚架上。

全天候结构允许真正的环境采样。

使用交流或直流电源运行。太阳能选项可用。

持续监控

E-BAM 通过连续采样和报告浓度数据来自动进行颗粒测量。数据记录每分钟更新一次。E-BAM 消除了过滤器收集和过滤器称重的相关过程，以及更昂贵、维护成本更高的仪器。随着环境监测采用 Beta 衰减，该过程变得简单、精简且成本低廉。

关于准确性

多年来，对环境细颗粒物进行实时准确、可靠和可重复的测量一直是环境监管机构和卫生专业人员难以实现的目标。Met One Instruments 开发了先进的颗粒物监测仪器，该仪器既可靠又易于操作。结果近乎实时地自动报告，无需高水平的人工干预。因为采样是在真实的环境条件下进行的，所以很容易检测到半挥发性有机化合物和硝酸盐，从而避免了颗粒物的测量不足。因此，E-BAM 将产生与手动参考方法相当的结果。

连续采样

E-BAM 是一种轻便的便携式仪器，无需外壳即可直接在恶劣环境中运行。坚固耐用的 E-BAM 便携式采样器系统可在 15 分钟内轻松安装。没有其他采样器能与 E-BAM 的便携性和灵活性相媲美。

设置

E-BAM 的快速启动是通过一系列提示来确保安装人员按照初始化顺序进行的。接下来，E-BAM 执行一系列自检诊断并提醒安装人员任何纠正措施。自检完成后，E-BAM 会自动将自身置于正常操作模式。

*请注意，即使安装程序只是打开 E-BAM，它也会使用默认设置值将自己置于正常运行状态。

颗粒大小选择

使用四个采样入口之一进行尺寸选择性浓度测量。E-BAM 可以与 TSP（总悬浮颗粒）、PM 10、PM 2.5 或 PM 1 入口一起提供和使用。使用一体式流量计、压力传感器和环境温度传感器来保持尺寸选择入口中与流量相关的切割点。PM 10 入口去除大于 10 微米的颗粒，入口不受风速和风向的影响。对于 PM 2.5 或 PM 1  ，使用第二个下游入口进行二级尺寸选择。

建造

E-BAM 的标准配置是一个独立的环境密封铝制外壳，放置在坚固的三脚架上。该系统可以永久放置在屋顶、道路附近、工业场所，或快速部署以监控紧急情况。“E”代表环保仪器。E-BAM 专门设计用于在没有额外保护的恶劣环境中工作。

直接现场报告

从现场远程收集实时或历史颗粒数据从未如此简单。通信选项包括固定电话或蜂窝数据调制解调器、视线扩频无线电以及非常偏远的站点的卫星通信。通过与数据记录器、PC 或笔记本电脑直接通信，可以轻松访问 E-BAM 数据。

可以使用其中一种通信选项检索存储的 E-BAM 数据；或者数据可能被转发到第三方数据采集系统。AIR Plus 软件支持 E-BAM 并提供完整的通信、数据库和带有图表的报告模块。Comet 数据检索软件包含在每个 E-BAM 中。

数字、模拟和报警输出

E-BAM 提供连续的数字和模拟输出。模拟输出可选择多个满量程电压。数字输出作为 RS-232 提供。提供单通道触点闭合报警继电器输出。这用于警告未指定的错误，例如；胶带破损、传感器故障、流量故障等。

报告模式

内部 E-BAM 数据记录器可以存储超过 182 天的每小时浓度数据以及来自多达 8 次其他测量的每小时平均数据。数字和模拟输出都可以轻松连接到其他数据记录系统。

易于操作

初始化后，E-BAM 将持续运行，校准验证期间除外。当前数据、历史数据和状态信息随时可用，不会中断正常的 E-BAM 操作。

数据验证

E-BAM 具有可选择的数据验证标准，包括但不限于：偏离滚动平均值、高值偏移和电源故障。如果发生错误，则将其与日期、时间和错误类型一起输入错误日志。

ADVANCED FEATURES

Accuracy and precision consistent with U.S. EPA requirements for Class III PM2.5 and PM10 measurement.

Real-time, accurate results without correction factors — regardless of season or geographic location.

Ambient sampling provides accurate measurement of semi-volatile nitrates and organic compounds.

Lightweight, rugged construction is easily mounted on a tripod in minutes.

All-weather construction allows for true ambient sampling.

Operates on AC or DC power. Solar power options available.

CONTINUOUS MONITORING

The E-BAM automates particulate measurement by continously sampling and reporting concentration data. Data records are updated every minute. The E-BAM eliminates the involved process of filter collection and filter weighing, and the more expensive, high maintenance instruments. With the adoption of beta attenuation for ambient monitoring the process has become simple, streamlined, and inexpensive.

ABOUT ACCURACY

Real-time accurate, reliable, and repeatable measurement of ambient fine particulate matter has been the elusive goal of environmental regulators and health professionals for many years. Met One Instruments has developed advanced particulate monitoring instrumentation which is both reliable and is easy to operate. Results are automatically reported in near real time, eliminating the need for high levels of human intervention. Because sampling occurs under true ambient conditions, semi-volatile organic compounds and nitrates are easily detected thereby avoiding under measurement of particulates. The E-BAM will therefore produce comparable results to the manual reference method.

CONTINUOUS SAMPLING

The E-BAM is a lightweight, portable instrument that operates directly in hostile environments without an exterior enclosure. The robust E-BAM portable sampler system is easily installed in less than 15 minutes. No other sampler matches the portability and flexibility of the E-BAM.

SET UP

Quick startup of the E-BAM is assured by a series of prompts guiding the installer on the initialization sequence to follow. Next the E-BAM performs a series of self-test diagnostics and alerts the installer of any corrective action. Upon completion of the self-tests, the E-BAM automatically places itself in normal operating mode.

*Note, even if the installer does nothing other than turn the E-BAM on, it will put itself in normal operation using default setup values.

PARTICULATE SIZE SELECTION

Size selective concentration measurements are made using one of four sampling inlets. The E-BAM may be supplied and used with either TSP (Total Suspended Particulate), PM10, PM2.5 or PM1 inlets. Flow dependent cut points in the size selective inlets are maintained using integral flow meter, pressure sensor and ambient temperature sensor. The PM10 inlet removes particles larger than 10 microns, the inlet is not affected by wind speed and wind direction. For PM2.5 or PM1 secondary size selection is made using a second downstream inlet.

CONSTRUCTION

The standard configuration of the E-BAM is a self-contained environmentally sealed aluminum enclosure placed on a rugged tripod. This system can be permanently placed on rooftops, near roads, at industrial sites, or rapidly deployed to monitor emergency situations. ‘E’ represents Environment Proof instrument. The E-BAM has been specifically designed to work in hostile environments with no additional protection.

DIRECT FIELD REPORTING

Remote collection of real time or historical particulate data from a field site has never been easier. Communication options include landline or cellular data modem, line of sight spread spectrum radio, and for very remote sites, satellite communications. E-BAM data is easily accessed by direct communication with a data logger, PC or laptop computer.

Stored E-BAM data may be retrieved using one of the communication options; or the data may be forwarded to third party data acquisition system. AIR Plus Software supports the E-BAM and provides a complete communication, data base and reporting modules with charting. Comet data retrieval software is included with every E-BAM.

DIGITAL, ANALOG AND ALARM OUTPUTS

The E-BAM provides continuous digital and analog outputs. The analog output is selectable to several full-scale voltages. Digital output is supplied as RS-232. A single channel contact closure alarm relay output is available. This is used for alert of an unspecified error such as; broken tape, sensor failure, flow failure, etc.

REPORTING MODES

The internal E-BAM data logger can store over 182 days of hourly concentration data as well as hourly averaged data from up to eight other measurements. Both digital and analog outputs are easily connected to other data recording systems.

EASY TO OPERATE

Once initialized, the E-BAM will operate continuously, except during calibration verification. Current data, historical data, and status information are available at any time without interrupting normal E-BAM operation.

DATA VALIDATION

The E-BAM has selectable criteria for data validation, including but not limited to; deviation from a rolling average, high value excursions, and power failure. Should an error occur, it is entered into the error log with date, time and type of error.
