GX-2009 Multigas Detector
RKI is proud to offer the smallest and lightest 4-gas monitor with an MSHA approval. MSHA (Mine Safety and Health Administration) approval allows this version of the GX-2009 to be used in underground mines, tunnels and excavations under MSHA jurisdiction. The GX-2009 Mining Version simultaneously monitors and displays % volume combustibles, oxygen, carbon monoxide, and hydrogen sulfide. MSHA Datasheet for more information GX2009, GX 2009
