WARNING

Read and understand this instruction manual

before operating instrument. Improper use of

the gas monitor could result in bodily harm

or death.

Periodic calibration and maintenance of the

gas monitor is essential for proper operation

and correct readings. Please calibrate and

maintain this instrument regularly!

Frequency of calibration depends upon the

type of use you have and the sensor types.

Typical calibration frequencies for most

applications are between 1 and 3 months, but

can be required more often or less often

based on your usage.

Introduction

Overview

The RKI Eagle is the most advanced portable gas detection system

available. The Eagle is built for rugged reliability and ease of use and

includes the latest innovations in gas detection technology:

• Simultaneous detection of one to six gases. Standard target gases

include combustible gas (% LEL and ppm), oxygen deficiency,

carbon monoxide, and hydrogen sulfide.

• Powerful sample-drawing pump with up to 125-foot range.

• Dot-matrix liquid crystal display (LCD) for complete,

understandable information at a glance.

• Microprocessor control for all functions, including data logging

and user-adjustable alarms.

• Visible and audible alarms for hazardous conditions and

malfunctions.

• Tough case with a balanced, light-weight design.

This version of the Eagle is set up for detection of flammable gases in

an inert environment (little or no oxygen). It will also detect oxygen,

carbon monoxide, and hydrogen sulfide. Your Eagle model may not

include all four sensors.

WARNING: The Eagle detects a combination of combustible gas,

oxygen deficiency, hydrogen sulfide and carbon

monoxide, or other toxic gases which can be lethal. When

using the Eagle, you must follow the instructions and

warnings in this manual to assure proper and safe

operation of the unit and to minimize the risk of

personal injury. Be sure to maintain and periodically

calibrate the Eagle as described in this manual.

About this Manual

This manual is intended for use with the Eagle. Examples used in this

manual are for a standard four-gas model (combustible gas, oxygen,

carbon monoxide, and hydrogen sulfide). This manual is organized as

follows:

• The standard sections included in pages 1 through 54 describe the

Eagle’s specifications and internal and external components. These

sections also describe the operation, calibration, and maintenance

of the Eagle.

• Appendix A lists part numbers for the Eagle’s replacement parts

and accessories.

• Appendix B describes the Eagle’s methane elimination feature.

• Appendix C describes the procedure to install the Eagle’s optional

Data Logger board.

4The PPM range represents the same range as 0 to 100% LEL for that gas. For example, 100% LEL for methane

= 5% by volume = 50,000 PPM. Therefore, the PPM range for methane is 0 to 50,000.
