Measurements
The Met One Instruments BAM-1020 PM10-2.5 (PMCoarse) Measurement System provides continuous
PM2.5, PM10 and PM10-2.5 particulate concentration
measurements from a single fully integrated system.
Two full-function BAM-1020 beta attenuation
particulate monitors are networked together in a
master/slave configuration using special back panel
connections and a serial network cable. Both units
are the latest revision models, with the accuracy and
detection limits required for the measurement.

The first U.S. EPA designated method for
PM10-2.5 continuous monitoring.
Both units are identical except for the BGI
VSCC cyclone on the PM2.5 inlet.
The coarse firmware has a simple menu
setting that determines which unit is the
PM10 master or PM2.5 slave in the system.
Each unit has its own 16.7 lpm flow system,
pump, and AT/BP sensor.
The master unit synchronizes the slave
clock automatically.
PM10 data and flow volumes are stored in
both standard and actual conditions!
Any errors or alarms in either unit are visible
in the master data file.
Function
Each hour, the master unit measures the PM10 concentration, collects the PM2.5 concentration from the other unit,
and calculates the PM10-2.5 concentration. The master unit stores and displays all three concentrations in actual
conditions, in addition to the PM10 value in standard conditions. The master unit also synchronizes the clock
timing between the two units, and monitors both units for errors. Any critical errors in either unit that would prevent
the master from accurately calculating the coarse data will generate an alarm.
Maximum Flexibility
The BAM-1020 PM10-2.5 system can be separated into two stand-alone PM10 or PM2.5 FEM monitors at any time!
Only a second cyclone is needed to operate both units in the popular PM2.5 FEM configuration. All other
accessories are already included in the BX-COARSE kit. This allows maximum flexibility should your coarse
monitoring requirements change in the future. In addition, existing PM2.5 FEM BAM-1020s can be configured into
a PM10-2.5 system by adding the BX-965 Report Processor back panels, network/clock cables, and the special PMCoarse firmware. Contact Met One for details.
Data Collection
Simply retrieve the digital array from the master unit, which contains all of the PM2.5, PM10, and PM10-2.5 data in a
single file. There is no analog output for PM10-2.5 value. The BAMs can be polled at any time without interruption.
Flow statistics files must be downloaded from each unit individually if needed.

Ordering Information
A single PM-Coarse BAM-1020 system order typically consists of two BAM-1020
units, two vacuum pumps (specify Medo or Gast), and one BX-COARSE accessory
kit. The BX-COARSE kit contains all of the required accessories for both units to be
operated for PM10-2.5 or PM2.5, with the exception of only one VSCC cyclone:
