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.
