RKI GX-3R 4 Gas Confined Space Monitor 72-RA-C

RKI GX-3R 4 Gas Confined Space Monitor (ATEX/CSA approved) is the smallest, and lightest CS Gas Monitor and includes a 3-year warranty on the monitor and sensors.

Weighing only 3.52 ounces, it clips comfortably within a worker's breathing zone. It simultaneously monitors and displays LEL combustibles, O2, CO, and H2S. H2S and CO are now available in a combo micro sensor. The LEL sensor has a unique design with two active filaments in one sensor to increase it’s resistance to silicone poisoning. If one filament gets poisoned the second filament takes over. The new O2 sensor is electrochemical with a 3 to 5 year life span.

Safety supervisors will appreciate the non-compliance indicator. The instrument flashes it’s 3 LED lights every 30 seconds.

Applications: Personal monitoring, Confined spaces, Refineries/petrochemical, Utilities, Oil and Gas, Water/wastewater, Fire services, Construction
