1 INTRODUCTION
1.1 About This Manual
This document is organized with the most important information toward the front of the manual,
such as site selection, installation, setups, and field calibrations, which all E-BAM owners and
operators should read and understand. Toward the back are sections that provide in-depth
information on subjects such as theory, diagnostics, accessories, and alternate settings. These
sections provide valuable information which should be consulted as needed. Electronic versions of
this manual are also available.
1.2 Technical Service
This manual is structured by customer feedback to provide the required information for setup,
operation, testing, maintaining, and troubleshooting of the E-BAM unit. Should support still be
required after consulting the printed documentation, contact one of the expert Met One Instruments,
Inc. technical service representatives during normal business hours of 7:00 a.m. to 4:00 p.m. Pacific
Standard Time, Monday through Friday. In addition, technical information and service bulletins are
often posted on the Met One Instruments, Inc. website. Please contact the service department and
obtain a Return Authorization (RA) number before sending any equipment back to the factory. This
allows for tracking and scheduling service work and to expedite customer service. Please have the
instrument serial number available when contacting the manufacturer.

The Met One Instruments, Inc. model E-BAM automatically measures and records airborne PM

particulate concentration levels using the principle of beta ray attenuation. This method
provides a simple determination of concentration in units of milligrams of particulate per cubic meter
of air. A small
14
C (Carbon 14) element emits a constant source of high-energy electrons known as
beta rays. Beta rays are detected and counted by a sensitive scintillation detector. A vacuum pump
pulls a measured amount of dust-laden air through the filter tape, which is positioned between the
source and the detector thereby causing an attenuation of the beta ray signal. The degree of
attenuation of the beta ray signal is used to determine the mass concentration of particulate matter
on the filter tape and the volumetric concentration of particulate matter in ambient air.
The E-BAM is designed as a simple, compact, and self-contained beta gauge, for portable
applications where rapid deployment and short interval real-time measurements are required. In
addition to the main housing, the monitor includes an external AC pump, a multi-parameter ambient
sensor, and a mounting tripod. See section 2.2 for a listing of standard and optional accessories.
