About the EAGLE 2
Using an advanced detection system consisting of up to six gas sensors, the EAGLE 2
sample draw gas monitor is capable of detecting the presence of combustible gas, oxygen
(O2), carbon monoxide (CO), hydrogen sulfide (H2S), and various other toxic gases
simultaneously. The EAGLE 2’s rugged, reliable, and easy-to-use design makes it ideally
suited for a wide range of applications, including sewage treatment plants, utility
manholes, tunnels, hazardous waste sites, power stations, petrochemical refineries, mines,
paper mills, drilling rigs, and fire fighting stations. The EAGLE 2 offers a full range of
features including:
• Simultaneous monitoring of one to six gases. The standard configuration includes four
sensors for combustible gas (%LEL, ppm, and %volume), oxygen, carbon monoxide
(CO), and hydrogen sulfide (H2S).
• Choice of three operating modes:
• Normal Mode for typical confined space or area monitoring. Normal Mode is the
standard factory setting.
• Bar Hole Mode for checking of bar holes when searching for underground gas
leaks
• Leak Check Mode for locating leaks in valves and piping
• Sample-drawing pump with up to 125 foot range
• Liquid crystal display (LCD) for complete and understandable information at a glance
• Ultrabright alarm LEDs
• Distinctive audible alarm for dangerous gas conditions or unit malfunction
• Microprocessor control for reliability, ease of use, and advanced capabilities
• Data logging functions (when used in Normal Mode)
• Alarm trend data (when used in Normal Mode)
• STEL and TWA (when used in Normal Mode) and over range alarms
• Peak readings (when used in Normal Mode)
• Built-in time function
• Lunch break feature
• RF shielded high impact plastic case
• CSA classified for Class I, Division I, Groups A, B, C, and D hazardous atmospheres

Case
The EAGLE 2’s sturdy, high-impact plastic case is radio frequency (RF) resistant and is
suitable for use in many environmental conditions, indoors and out. The case is dust proof
and water resistant. It’s two main components, the top case and bottom case, are held
together with three screws located on the bottom case. The interface between the top case
and bottom case is gasketed. A sturdy, well balanced handle on the top case allows you to
hold the instrument comfortably. A clear plastic window is located on the top case to the
front of the handle for viewing the LCD.
A removable battery case is located at the rear of the bottom case. A thumbscrew secures
the battery case to the bottom case. The interface between the battery case and the bottom
case is gasketed. Six raised feet on the bottom of the case, four on the bottom case and two
on the battery compartment, raise the EAGLE 2 slightly from the surface on which it rests.
Sensors
The EAGLE 2 uses up to six sensors to monitor combustible gas, oxygen (O2), carbon
monoxide (CO), hydrogen sulfide (H2S), and various other toxic gases simultaneously.
The sensors are located inside the EAGLE 2 bottom case and are installed in the flow
chamber. The sensors described below are the four standard sensors. See “Appendix D:
PID Sensors” for a description of the PID sensors, “Appendix E: ESM-01 Toxic Sensors”
for a description of the ESM-01 toxic sensors, “Appendix F: TC Sensors” for a description
of the TC sensors, “Appendix G: Infrared Carbon Dioxide Sensors” for a description of
the IR CO2 sensors, “Appendix H: Infrared Methane Sensor” for a description of the IR
methane sensors, and “Appendix I: Infrared Hydrocarbon Sensor” for a description of the
IR hydrocarbon sensor. The standard sensors use different detection principles as
described below.
Catalytic Combustible Gas Sensor (LEL Sensor)
The catalytic combustible gas (LEL) sensor detects combustible gas in the %LEL range. It
uses a catalytic element for detection. The reaction of gas with oxygen on the catalyst
causes a change in the resistance of the element which changes the current flowing
through it. The current is amplified by the EAGLE 2’s circuitry, converted to a
measurement of combustible gas concentration, and displayed on the LCD.
The LEL sensor housing includes a sintered metal flame arrestor on one end that allows
gas to diffuse into the sensor. On the other end, five pins extend from the sensor. The
sensor cable connects to these pins on one end and terminates in a four-position connector
on the other end which plugs into the HC socket on the main PCB (see “Main PCB” on
page 19).
Oxygen Sensor
The O2 sensor is a galvanic type of sensor. A membrane behind the openings on the sensor
face allows gas to diffuse into the sensor at a rate proportional to the partial pressure of
oxygen. The oxygen reacts in the sensor and produces a voltage proportional to the
concentration of oxygen. The voltage is measured by the EAGLE 2’s circuitry, converted
to a measurement of gas concentration, and displayed on the LCD.
The sensor includes a short cable that terminates in a round 7-position connector. It mates
with the OXY pins on the main PCB (see “Main PCB” on page 19).
16 • Instrument Description EAGLE 2 Operator’s Manual
CO and H2S Sensors
The CO and H2S sensors are electrochemical sensors that consist of three precious metal
electrodes in a dilute acid electrolyte. A gas permeable membrane covers the sensor face
and allows gas to diffuse into the electrolyte. The gas reacts in the sensor and produces a
current proportional to the concentration of the target gas. The current is amplified by the
EAGLE 2’s circuitry, converted to a measurement of gas concentration, and displayed on
the LCD.
The CO and H
S sensors are physically very similar. Except for their markings and wire
2
colors, they look almost identical. A three-position connector at the end of a 2-wire cable
from each sensor plugs into a socket on the main PCB. The sockets on the main PCB for
the CO and H
S sensors are labeled CO and H2S. Normally, the CO connector plugs into
2
the CO socket and the H2S plugs into the H2S socket. However, because of the way that
the main PCB circuitry is arranged, if the CO sensor is plugged into the H2S socket and
the H2S sensor is plugged into the CO socket, the sensors will still operate properly and
the CO and H2S readings will still appear on the channels that are programmed for those
gases.
LCD
A digital LCD (liquid crystal display) is visible through a clear plastic window in the top
case. The LCD simultaneously shows the gas reading for all installed sensors. The LCD
also shows information for each of the EAGLE 2’s operating modes.
Control Buttons
Four control buttons are located below the LCD. They are, from left to right, POWER

Connectors for the sensors, differential pressure switch, pump, display PCB, optional float
probe, and I.S. barrier PCB are located on the main PCB. In addition, an IR transmitter/
receiver is located at the front of the PCB behind the IR port on the front of the bottom
case.
Alarm LEDs
Two sets of red alarm LEDs (light emitting diodes) are visible through two raised, frosted
plastic lenses in the top case. Each set has two LEDs. They are above the LCD, one above
the left corner and one above the right corner. The alarm LEDs alert you to gas, low
battery, and failure alarms.
Infrared Communications Port
An infrared (IR) communications port is located on the left front of the bottom case when
the instrument is viewed from the front. The data transmitted through the port is in
standard IrDA protocol. A computer’s infrared port or an IrDA/USB cable connected to a
USB port can be used to download data saved by the EAGLE 2 to a computer using the
Eagle 2 Data Logger Management Program. See the Data Logger Management Program
operator’s manual for data logging and downloading instructions.
EAGLE 2 Operator’s Manual Instrument Description • 19
Buzzer
A solid-state electronic buzzer is located on the front of the top case. It is a panel mounting
type of buzzer and is water resistant and sealed to the inside of the top case with an O-ring.
The buzzer sounds for gas alarms, malfunctions, low battery voltage, and as an indicator
during use of the EAGLE 2’s many display and adjustment options.
Battery Case & Batteries
Four C-size alkaline batteries (standard) or optional rechargeable
C-size Ni-MH batteries power the EAGLE 2. They are installed in the battery case which
is located at the rear of the bottom case. The battery case is secured to the bottom case
with a thumbscrew.
Instrument run time is dependent upon battery type. At 25°C, alkaline batteries power the
EAGLE 2 for 16 hours of non-alarm operation. Ni-MH batteries will power the EAGLE 2
for 18 hours of non-alarm operation. The current battery voltage is viewable in Display
Mode (see “Display Mode” on page 41).
When the EAGLE 2 detects low battery voltage, a low battery warning is activated. When
battery voltage is too low for operation, the EAGLE 2 sounds a dead battery alarm.
The alkaline or Ni-MH batteries can be accessed for replacement by unscrewing the
thumbscrew that secures the battery case to the bottom case and pulling the battery case
away from the bottom case. The Ni-MH batteries can be recharged by using the EAGLE 2
charger (see “Replacing or Recharging the Batteries” on page 69).
NOTE: Use of batteries or battery chargers not specified by RKI Instruments, Inc. will
void the CSA classification and may void the warranty.
WARNING: To prevent ignition of a hazardous atmosphere, batteries must only be
changed or charged in an area known to be nonhazardous.
Flow System
The EAGLE 2 flow system consists of the inlet fitting, hydrophobic filter, pump, internal
tubing, differential pressure (DP) switch, sensor chamber, charcoal filter, and exhaust
fitting.
Inlet Fitting
The inlet fitting is on the right front (when viewed from the front) of the bottom case. It is
a nickel plated brass quick connect fitting. It mates with either the sample hose or with the
hydrophobic probe.
Hydrophobic Filter
The hydrophobic filter is located in the bottom case above the sensors. Normally the
hydrophobic probe accessory (see “Hose and Probe” on page 21) will prevent water and
particulate contamination from entering the flow system, but if the probe is not used, the
hydrophobic filter will stop water and particulates from penetrating further into the flow
system. If it becomes dirty or water logged, replace it (see “Replacing the Hydrophobic
Filter” on page 73).
Pump
A diaphragm pump inside the rear of the bottom case draws the sample to the sensors. It
can draw sample from as far as 125 feet from the EAGLE 2.
CAUTION: Sample hose lengths of more than 125 feet are not recommended for the
20 • Instrument Description EAGLE 2 Operator’s Manual
EAGLE 2 because of flow rate reduction and increased response time.
Consult RKI Instruments, Inc. for sample hose lengths longer than 125 feet.
Internal Tubing
The flow system includes polyurethane tubing to route the sample between the various
components of the flow system. The internal sample tubing is not user serviceable.
Differential Pressure (DP) Switch
The DP switch is inside the front of the bottom case. It senses the EAGLE 2’s flowrate by
monitoring the pressure drop between points in the flow system. When the flowrate
becomes too low for safe operation of the EAGLE 2, a set of contacts inside it open and
the EAGLE 2 indicates a low flow alarm.
Sensor Chamber
A PVC block in the bottom case is configured to accept the four gas sensors. It routes the
sample to each sensor. The LEL sensor and the oxygen sensor are retained in the sensor
chamber by brackets. The CO and H2S sensors are each pushed past two sealing O-rings
into the chamber and are retained by the O-ring compression force.
Charcoal Filter
The charcoal filter is located in the front of the flow chamber next to the CO sensor. It
contains activated charcoal. The CO sensor will respond if exposed to H2S and certain
hydrocarbon gases. The charcoal filter scrubs these gases out of the sample to avoid false
CO readings. If false or elevated CO readings are noticed, especially in the presence of
S, change the charcoal filter. The charcoal inside the filter cannot be replaced; the entire
H
2
filter must be replaced.
Exhaust Fitting
The exhaust fitting is located below the inlet fitting. It routes the gas sample out of the
EAGLE 2. It includes a female 10-32 thread that can be used for the installation of a hose
barb or other type of fitting that has a male 10-32 thread so that the exhaust can be routed
to a particular location with flexible tubing if desired.
Standard Accessories
Standard accessories include the shoulder strap, the sample hose, and the hydrophobic
probe.
Shoulder Strap
A comfortable elastic shoulder strap clips to the EAGLE 2 at the front and rear of the top
case. It clips to stainless steel rings that are installed in features on the top case. It can be
removed from the EAGLE 2 by opening the clip at each end of the strap and removing it
from the strap ring at the front and rear of the top case.
Hose and Probe
A 5 foot polyurethane sample hose and a 10 inch hydrophobic probe are included as
standard. The hose has a male quick connect fitting on one end and a female quick connect
fitting on the other end. The probe has a male quick connect fitting. Normally, the male
end of sample hose is installed in the EAGLE 2 inlet fitting and the probe is installed in
the female end of the hose. However, if the sample hose is not needed for monitoring a
particular area, the probe may be installed directly to the inlet fitting. Sample hose lengths
EAGLE 2 Operator’s Manual Standard Accessories • 21
are available from 5 feet (standard length) to 125 feet (see “General Parts List” on
Sample Hose
Probe
page 79). A Teflon lined hose is provided with all units that contain a PID sensor. This
hose must be used when operating a PID EAGLE 2 (see “Appendix D: PID Sensors” on
page 125).
CAUTION: Sample hose lengths of more than 125 feet are not recommended for the
EAGLE 2 because of flow rate reduction and increased response time.
Consult RKI Instruments, Inc. for hose lengths longer than 125 feet.
The probe includes a replaceable particle filter and hydrophobic filter disk that prevent
particulates and water from entering the EAGLE 2’s flow system. See “Replacing the
Hydrophobic Probe’s Particle Filter and Hydrophobic Filter Disk” on page 72 for
instructions to replace the particle filter and hydrophobic filter disk.
NOTE: When using the probe with a PID EAGLE 2, be sure that the particle filter is not
installed.

Optional Accessories
AC Adapter
Charging Module
Several optional accessories are available for the EAGLE 2. They include rechargeable
Ni-MH batteries, battery chargers, various special probes, and dilution fittings. The most
commonly used optional accessories are described below. Detailed instructions regarding
the use of these and other available accessories are included in other parts of this manual.
Data logging accessories are briefly described in “Data Logging” on page 52.
Rechargeable Ni-MH Batteries
Rechargeable Ni-MH batteries are available for the EAGLE 2. A fully charged set of NiMH batteries will power the EAGLE 2 for 18 hours. The batteries will last for a minimum
of 500 charge cycles. See “General Parts List” on page 79 for ordering information.
Battery Chargers
Three battery chargers are available for the EAGLE 2 to charge the optional Ni-MH
batteries, the standard AC charger, a DC charger with a vehicle plug adapter, and an AC/
DC charger with a vehicle plug adapter.
AC Charger
The standard AC charger consists of the charging module, which includes all of the
charging circuitry, and an AC adapter. The charging module includes a five foot cable with
a connector on the end that mates with the EAGLE 2 charging socket. The AC adapter
plugs into a 115 VAC wall outlet and connects to the charging module with a jack on the
end of a five foot DC output cable. The AC adapter will also work for 100 VAC or 220
VAC if an appropriate plug adapter is provided. The AC charging station is shown below
in Figure 7.

Optional Probes
Various optional probes designed for specific applications are available for the EAGLE 2.
They include the following:
• 30 inch aluminum probe
Figure 9: 30 Inch Aluminum Probe
This probe is designed for applications where it is necessary to put the probe tip in
areas that are out of reach with the standard probe. A small breather hole near the end
of the probe tube prevents interruption of sampling and a low flow alarm if the probe
tip is blocked.
• 30 inch stainless steel probe
24 • Optional Accessories EAGLE 2 Operator’s Manual
Figure 10: 30 Inch Stainless Steel Probe
This probe is physically the same as the 30 inch aluminum probe and is intended for
applications where a high level of corrosion resistance is required in the long probe
tube.
• 4 foot stainless steel probe
Figure 11: 4 Foot Stainless Steel Probe
This probe is designed for areas where it is necessary to put the probe tip in areas that
are out of reach for even the 30 inch probes. A stainless steel probe tube is used
because the length of the probe tube requires a high degree of rigidity. Stainless steel is
more rigid than other normally used materials. A small breather hole near the end of
the probe tube prevents interruption of sampling and a low flow alarm if the probe tip
is blocked.
• Barhole probe
Figure 12: Barhole Probe
This probe is designed specifically for barhole testing. See “Appendix K: Using the
EAGLE 2 in Bar Hole Mode” for an in-depth discussion of using the EAGLE 2 in Bar
Hole Mode.
• 10 inch probe with dust filter
Figure 13: 10 Inch Probe With Dust Filter
This probe is designed for use where drawing water or moisture into the EAGLE 2 is
not a concern. Instead of a hydrophobic filter, a cotton dust filter is used.
• 32 inch telescoping probe with dust filter
Figure 14: 32 Inch Telescoping Probe with Dust Filter
This probe is designed for use where it is necessary to put the probe tip in areas not
accessible with the 10 inch probe with dust filter and applications where the probe tube

See “General Parts List” on page 79 for probe ordering information.
External Dilution Fittings
Two external dilution fittings are available for the EAGLE 2, a 1:1 dilution fitting and a
3:1 dilution fitting. They are designed to mate with the inlet fitting and accept a sample
hose or probe. The fittings are made with brass and nickel plated brass and are appropriate
for use with the four standard gases. The 1:1 fitting is normally used when it is necessary
to introduce air into a sample that has no oxygen or a very low level of oxygen, such as a
nitrogen purged sample. Both the 1:1 and 3:1 fittings can also be used when one of the
target gas levels in the sample area will likely be present in a concentration above the
detection range for that gas. Since the fittings partially consist of unplated brass, they are
not appropriate for detection of elevated levels of H2S or of gases that are easily absorbed
such as Cl2 or SO2.
