RKI GX-9000 Marine Gas Monitor Configuration:O2/IR CH4 (%LEL/%vol) The 408 Double Valve PumpThe RKI GX 9000 is a rugged, configurable marine gas monitor built for tanker, refinery, and confined space entry work, drawing samples through catalytic, NDIR, thermal conductivity, and electrochemical sensors depending on the gas package selected. Sensor combinations span standard confined space gases (O2, CO, H2S) alongside hydrocarbon, methane, chlorine, and CO2 detection in both diffusion and IR based ranges.
