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.
