Eagle : Portable Gas Monitor

RKI is proud to produce the most versatile portable gas detector on the market. 
The EAGLE is a powerful instrument that does more than offer standard confined 
space protection. The EAGLE also provides detection combinations never before offered 
in a portable gas monitor featuring the industry’s widest selection of high quality, 
long life and field proven sensors.

The EAGLE’s ergonomic design offers easy access to controls such as autocalibration, 
alarm silence, demand zero, peak hold and a wide variety of other features. Each channel
has 2 alarm levels plus TWA and STEL alarms for toxic channels. Alarm levels are 
adjustable and can be latching or self resetting.

Standard features on the EAGLE are not available on most other competitive units 
such as PPM/LEL hydrocarbon detection (5 ppm resolution) and a methane elimination 
switch for environmental applications. For quick response and recovery, the EAGLE has
 a strong internal pump which can draw samples from over 125 feet. The EAGLE will con-tinuously 
operate for over 30 hours on alkaline batteries or 18 hours on Ni-Cads. Many accessories such 
as long hoses, special probes, datalogging, continuous operation adapters, remote alarms and strobes, 
dilution fittings, inter-nal hydrophobic filter, etc, are available to help satisfy almost any application. 
Rugged, weather resistant, easy to operate and maintain, the EAGLE is the industry’s answer to 
portable gas detection in many applications, including land surey.


Weather resistant, chemical resistant, RF/EMI coated high impact polycarbonate polyester blend. Can be set in rain or into 2.5 inches of water without damage. Ergonomically balanced with rugged top mounted handle.
