1 INTRODUCTION
1.1 About This Manual
This document is organized with the most important information toward the front of the manual. All
users should read and understand the sections on setup, operation, and field audits. Toward the
back are sections that provide in-depth information on subjects such as diagnostics and
accessories. These sections should be consulted as needed.
This manual is periodically revised for maximum accuracy and to incorporate new features or
updates. User feedback is welcome. Electronic versions of this manual are available upon request.
1.2 Technical Service
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 our website. Please contact us and obtain a Return
Authorization (RA) number before sending any equipment back to the factory. This allows us to
track and schedule service work and to expedite customer service.

Please have the instrument serial number available when contacting the manufacturer. On most
models manufactured by Met One Instruments, it will be located on a silver product label on the unit,
and printed on the calibration certificate. The serial number will begin with a letter and be followed
by a unique five digit number such as U15915.

1.3 E-FRM-DC: Environmental Federal Reference Method Sampler
Figure 1-1 E-FRM-DC Air Sampler
The Met One Instruments, Inc. Model E-FRM-DC is a programmable single-event filter sampler
designed to meet federal specifications as a reference method for the determination of daily PM
2.5
or
PM
10
particulate concentrations in ambient air.
It employs a single pre-weighed 47 mm sample filter disc in an EPA-standardized cassette which
must be manually exchanged by the operator prior to each sample period. The instrument runs a
sample period based on an operator programmed start time and sample duration.
A vacuum pump, controlled to 16.67 liters-per-minute, draws ambient air through a series of
standardized inlets that provide the PM
2.5
or PM
10
cut points. The sample then passes through the
filter, where the airborne particulate matter is deposited.
The dirty filter is collected after the sample period and sent to a lab to be equilibrated and reweighed
per the standardized EPA gravimetric procedures. The resulting clean and dirty mass values for the
filter are then correlated to the volume of air sampled to determine the concentration of particulate in
micrograms-per-cubic-meter (µg/m3)
The E-FRM-DC can easily be configured for reference method PM
2.5
sampling using the
standardized BGI VSCC™ very-sharp-cut cyclone or the classic WINS Impactor.
Page 10 E-FRM-DC-9800 REV A
Alternatively, other sharp-cut cyclones can be installed for non-designated or indicative PM2.5 or
PM1 sampling.
If PM
10
monitoring is desired, the PM
2.5
cyclones can be omitted entirely, and a pass-through
adapter can be installed in its place.
1.3.1 E-FRM-DC U.S. EPA Configurations
The
E-FRM-DC
is US-EPA designated under the following designation numbers:
• RFPS-0315-221: PM
2.5
designation
• RFPS-0216-231: PM
10
designation
• RFPS-0316-232: PM
10-2.5
designation
US-EPA designated methods using the E-FRM-DC are modified occasionally to reflect hardware or
software improvements. These modifications do not impact previously designated configurations of
the E-FRM-DC but may provide the end user with a product upgrade path that will allow the monitor
to continue to be operated as a US-EPA designated method. For further details, please contact our
service department. Details concerning USEPA designated configurations of the E-FRM-DC may be
found on the US-EPA website.

PM
10
Sampling Config: Pass-through tube (used in place of cyclone) included for PM
10
sampling.
Other Configurations: Compatible with PM
2.5
or PM
1
SCC cyclones. TSP inlet available.
Filter Type: 47mm PTFE disc filters standard. Other filter material types available.
Filter Holder: Accommodates standard EPA-pattern white Delrin filter cassettes.
Filter Temp Control: Filter Temp within 5°C of ambient during sampling and standby. Logged in data.
Operating Temperature: -30 to +50°C Ambient
Operating Pressure: 400 to 800 mmHg, Ambient
Sample Events: 24 hour samples standard. Programmable start date/time and duration.
Flow Rate: 16.67 L/min (1 m
3
/hr.). With flow sensor and real-time actual flow control.
Flow Accuracy: ±2% (±.33 L/min)
Flow Records: Flow rate, temperature, pressure logged in 5 minute intervals.
Vacuum Pump: Single-head diaphragm 12 VDC pump

Compatible Software: FSCommAQ
User Interface: 4.3” graphical touch screen
Enclosure Type: Active fan ventilation
Deployed Dimensions: 2.0 meters (78.75”) high, 65.5 cm (25.75”) wide, 64.1 cm (25.25”) deep
Footprint Dimensions 65.5 cm (25.75”) wide, 64.1 cm (25.25”) deep
Weight: Sampler 33 Ib (except PM
10
inlet head); Stand 10.5 Ib

* The approximate upper concentration limit is based on the sampler’s ability to maintain 16.67 L/min sample flow over the entire 24 hour period,
despite PTFE filter loading with typical urban PM
2.5
particulate. Actual concentration limits will vary depending on ambient conditions, altitude, and
particulate type.
Specifications may be subject to change without notice.
