Gas Detection for Life

Gas Detection for Life

Not only will RKI’s gas detection equipment protect your life and property from the hazards of gases and vapors, but with proper care, it may also be the last gas detector you will ever need to purchase.


For over 80 years, RKI Instruments has been at the forefront of sensor technology, developing advanced detection techniques to provide solutions for specific applications. As a result, RKI provides reliable, rugged gas detection equipment. Through ingenuity and years of industry experience, RKI has developed a unique line of gas detection interments and accessories, and we are proud to offer them to you here at Haaker Underground.

6 Gas Sample Drawing Monitor

The Eagle 2 features a PID sensor for detecting high or low ppm levels (0-50 or 0-2,000) of VOC gases; % volume capability of CH4 and H2 using a TC (thermal conductivity) sensor; PPM or LEL hydrocarbon detection at the push of a button; infrared sensors for CO2 (ppm or % volume), methane or hydrocarbons in LEL and % volume ranges; methane elimination feature for environmental applications; and a variety of super toxic gases. The Eagle 2 has a strong internal pump with a low flow auto pump shut off and alarm, which can draw samples from up to 125 feet. The Eagle 2 will continuously operate for over 18 hours on alkaline batteries or 20 hours on niMH. Datalogging is a standard feature for all sensors on all versions.

Multi-Gas Detector

The GX-2012 is RKI’s smallest personal 1-5 sensor gas monitor with a built-n sample pump. Having 3 operating modes, the GX-2012 can be used for confined space, safety monitoring in its Normal Operating mode, for leak investigation in Leak Check mode and for underground leak checking in Bar Hole mode. When equipped with an optional TC sensor, the GX-2012 can measure 100% volume methane and dynamically auto range from % LEL to % volume. This is ideal for line purge testing.
