The GX-3R simultaneously monitors and displays LEL combustibles, O2, CO (H2 compensated CO also available) and H2S. The LEL sensor has a unique design with two active filaments in one sensor to increase its resistance to silicone poisoning. If one filament gets poisoned the second filament takes over.
