E-BAM stands for Environmental Beta Attenuation Monitor, it is a light-weight and portable monitoring station manufactured by Met One Instruments for ambient particulate matter, dust and haze pollution using state-of-art beta attenuation measurement principle, a method certified by USEPA as one of the Federal Equivalent Method (FEM) for particulate matter monitoring.
E-BAM Plus is a portable, real-time beta gauge which has EPA Approval for PM10 particulate measurements. The E-BAM Plus will satisfy users, regulators and those from the health community by providing truly accurate, precise, real time measurement of fine particulate matter automatically. It is a rugged, portable, battery operated package easily deployed and operational in 15 minutes.
The E-BAM Plus automates particulate measurement by continuously sampling and reporting concentration data. Data records are updated every minute. The E-BAM Plus eliminates filter collection and filter weighing, and the expense of high maintenance instruments. With the adoption of beta attenuation for ambient particulate monitoring it has become simple, streamlined, and inexpensive.
The E-BAM Plus is a robust, lightweight, portable instrument that operates directly in hostile environments without an exterior enclosure; easily installed in less than 15 minutes. No other sampler matches the Designated performance, portability and flexibility of the E-BAM Plus.

ABOUT E-BAM PLUS'S 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. The E-BAM Plus is reliable and is easy to operate. Results are automatically reported in near real time with no 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 Plus will produce comparable results to the manual reference method.
DATA REPORTING & COMMUNICATIONS
The E-BAM Plus 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.
The internal E-BAM Plus data logger can store over 484 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.
Remote collection options include landline or cellular data modem, CCS Cloud reporting, line of sight spread spectrum radio, and for very remote sites, satellite communications. E-BAM Plus data is easily accessed by direct communication with a network, data logger, PC or laptop computer.
Stored E-BAM Plus data may be retrieved using one of the communication options, USB Flash Drive; or the data may be forwarded to third party data acquisition system. AIR Plus Software supports the E-BAM Plus and provides a complete communication, data base and reporting modules with charting. Comet data retrieval software is included with every E-BAM Plus.
SIZE SELECTIVE SAMPLING INLETS
Size selective concentration measurements are made using a variety of sampling inlets. The E-BAM Plus can be supplied with TSP (Total Suspended Particulate), PM-10 or PM2.5 inlets. Flow dependent cut points in the size selective inlets are maintained using integral flow meter, pressure sensor and ambient temperature sensor.
The PM-10 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.
