When making a confined space entry, experienced teams know how important it is to have a reliable topside monitor. It's a critical part of both pre-entry and an "active-passive" monitoring procedure during entry. Confined space entry teams that value reliability often turn to RKI Instruments for their high-quality gas monitoring devices. RKI produces the GX-2012 which is an active, pumped 4-gas monitor with sensors to detect Hydrogen Sulfide (H2S), combustible gases (LEL), Carbon Monoxide (CO), and Oxygen (O2). The strong internal pump of the GX-2012 can pull samples from up to 50 ft. away. This makes it an ideal topside monitor that can be run continually while a team is deployed doing water treatment facility work, work in sewers, silos, or other potentially hazardous locations. For the confined space entrants, a diffusion monitor is part of any comprehensive safety program. While the topside monitor can confirm the initial entry conditions are acceptable, winding or compartmentalized structures may contain micro-atmospheres that won't be picked up until the worker comes in contact with the gas. RKI Industries also makes a top-rated 4-gas diffusion monitor, the GX-2009. The GX-2009 makes an ideal passive component to your "active-passive" gas detection program because it's so small and so light. Workers aren't encumbered with a bulky detection device while trying to complete their tasks. And like the GX-2012, it's a monitor that will lower the overall cost of ownership because of its reliability and durability over time.
