RKI is proud to introduce and 
announce the release of our new product, the EAGLE 2. Building on the strong success of the popular EAGLE series.
The 2010 Winter Olympics Cauldron was built with a fixed gas detection system using RKI’s products. A Beacon 410 controller and four Direct Connect LEL sensors were installed inside the arms of the
outdoor cauldron.
RKI’s H2 sensors were also used inside the fuel cell buses that transported athletes and spectators, and in the garages and terminals where the buses were used
The GD-70D is a compact transmitter for detection of toxic gases, oxygen, or combustible gases and vapors. This new smart gas detection transmitter series sets a new standard for performance, flexibility, and versatility. The GD-70D sample-draw transmitter offers an array of sensor technologies unmatched in the industry, including unique offerings, such as our hydrogen-specific ppm and LEL versions.
