Eagle Instruction Manual Introduction • 1

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 100-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.

•UL and CSA classiﬁed. Intrinsic safety for Class I, Division I,

Groups A, B, C, and D hazardous atmospheres (standard 4-gas

model and non-standard toxic gas versions). Consult RKI

Instrument, Inc., for classiﬁcation of other Eagle versions.

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

WARNING: The Eagle detects a combination of combustible gas,

oxygen deﬁciency, hydrogen sulﬁde and carbon

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

must follow the instructions and warnings in this

manual to assure proper and safe operation of the Eagle.

2 • Introduction Eagle Instruction Manual

About this Manual

This manual is intended for use with all Eagle models. Examples used

in this manual are for the standard four-gas model (combustible gas,

oxygen, carbon monoxide, and hydrogen sulﬁde). Differences

between the standard four-gas model and other Eagle models are

noted where applicable. This manual is organized as follows:

• The standard sections included in pages 1 through 49 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.

• Appendices C through E describe the Eagle’s non-standard

sensors.

• Appendix F describes the Eagle tank tester model.

• Appendix G describes the Eagles’s ﬁve- and six-gas models.

• Appendix H 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.
