Personal Sample Draw, 4 instruments in 1 monitor
Built around high-quality micro-sensor technology, the GX-2003 is RKIs smallest personal 4-in-1 gas monitor with a built in sample pump. Weighing only 11 ounces, it has many features which set the GX-2003 apart from the competition. For example, it can monitor the standard confined space gases (LEL combustibles, Oxygen content, Carbon Monoxide, and Hydrogen Sulfide), and it can also measure 100% volume Methane and dynamically display either % LEL, or % volume with its auto-ranging ability.

The GX-2003s large LCD display shows all gas readings, battery level, current time, and will automatically backlight in alarm conditions. This unit also has a special bar hole mode to facilitate locating underground gas leaks. A high sensitivity leak check mode is also included, and provides ppm level detection of gas leaks. A special variable frequency alarm helps to pinpoint the leak without looking at the instrument display. Other standard mode alarm types include vibration, visual, and audible alarms that can be set to latching or non-latching. Controlled by a microprocessor, the GX-2003 continuously checks itself for sensor connections, low battery, circuit trouble, low flow, and calibration errors. The GX-2003 can interchangeably operate on either a Ni-MH battery pack or 3 AA alkaline batteries. The batteries are simple to replace requiring no tools to access the battery compartment. The Ni-MH battery pack can receive a charge directly within the instrument or separately, allowing the unit to remain in service.
Calibration intervals and reminders are user adjustable and can be set to either go into alarm or to lock the user out of normal measurement mode once a calibration period has expired. Calibrations can be performed automatically or individually in single calibration mode. The GX-2003 is also compatible with the economical SM-2003 single channel calibration station.

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.
