Tanker Tester Gas Monitor

RKI is pleased to offer the most versatile portable gas detector specifically for maritime tankers. 
The EAGLE provides detection combinations never before offered in a portable gas monitor featuring 
gases like % LEL and volume of hydrocarbons, oxygen, as well as PPM levels of hydrogen sulfide.
The EAGLE features include an infrared sensor for combustible gas monitoring in inerted tanks, and
dual hydrophobic filters to increase its water resistant performance. For quick response and recovery
 from distant sampling locations, the EAGLE has a strong internal pump with low flow auto shut off and
 alarm. The pump can draw samples up to 125 feet even with the dual hydrophobic filters in place. 
The EAGLE will continuously operate for over 30 hours on alkaline batteries or 18 hours on Ni-Cads. 
A variety of accessories are also available to help satisfy almost any application such as long sample
 hoses, datalogging, continuous operation adapters, remote alarms and strobes, extra loud buzzer and 
alkaline recognition battery charger. The marine versions of the Eagle also include an internal oil mist filter 
to protect the sampling system.

With its ergonomic design and large glove friendly buttons, the EAGLE offers easy access to controls 
such as autocalibration, alarm silence, demand zero, peak hold and a wide variety of other features and 
settings. Each channel has two alarm levels. The two alarm levels are user adjustable and can be latching 
or self resetting. Rugged, reliable, easy to operate and maintain, the EAGLE is the solution for testing HC 
vapor levels in inerted tanks. Also, a special version can detect H2S levels up to 1,000 ppm.


Weatherproof, chemical resistant, RFI / EMI coated high impact polycarbonate-polyester blend. Can operate in rain or set into 2.5” of water without damage. Ergonomically balanced with rugged top mounted handle.
