RKI GX-2012


GX2012, 4 Gas LEL/02/H2S/C0 base, choose battery option



Lightweight, intrinsically safe, and able to sample air from over 50 ft. away, the GX-2012 is a great choice for dependable 4-gas monitoring. The GX-2012 features micro-sensor technology that adds to the lightweight design. The ability to use it for gas line purge testing makes it more functional than many other gas monitors on the market.

While the GX2012 can be configured to measure percentage of volume of methane (CH4), most of our customers like the reliable sensor technology and dependable electronics of this monitor for confined space 4-gas testing.

The GX-2012 is built to measure the gases OSHA requires for confined space entry: Oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S) and the Lower Explosive Levels of a range of combustibles (LELs). The powerful internal pump is capable of drawing samples from a distance of up to fifty feet, making it great for sewer entry and other distance confined space sampling work. Intrinsically safe and built with petrochemical (oil rig/refinery) and waste water treatment facility workers in mind, the GX-2012 is ideal for tank cleaners and technical rescue workers too.

Properly deployed, the GX-2012 meets OSHA standards for confined space gas monitoring. It is also CSA classified as intrinsically safe and meets Class I, Division 1, Groups A, B, C, D: TIIS, IECEx, ATEX, CE.
