RKI Instruments GX-2012 Confined Space 4-Gas Detector 72-0290-22

Lightweight, intrinsically safe, and able to sample air from over 50 ft. away, the GX-2012 is a great choice for dependable 4-gas monitoring.

While the GX2012 can be configured to measure %of Volume of Methane (CH4) most of our customers like the reliable sensor technology and dependable electronics of this monitor for confined space 4-gas testing.

• 10 ft. sample hose
• Probe
• Operators manual
• Product CD (contains training video, parts list, data logging software, operators manual, and quick reference card)
• Chosen battery option

• 34 L cylinder of calibration gas (H2S@25 ppm/CO/CH4/O2)
• Demand flow regulator
• Carrying case
• Tubing

The GX-2012 is built to measure the gases OSHA requires for confined space entry: Oxygen (O2), Carbon Monoxide (CO), Hydrogen Sulfide (H2S) and the Lower Explosive Levels of a range of combustibles (LELs). The powerful internal pump is capable of drawing samples from a distance of up to fifty feet, making it great for sewer entry and other distance confined space sampling work.

Properly deployed, the GX-2012 meets OSHA standards for confined space gas monitoring. It is also CSA classified as intrinsically safe and meets Class I, Division 1, Groups A, B, C, D: TIIS, IECEx, ATEX, CE.

The GX-2012 features micro-sensor technology that adds to the lightweight design. The ability to use it for gas line purge testing makes it more functional than many other gas monitors on the market.

• LEL, O2, CO and H2S gas sensors
• Percentage by volume methane detection can be added
• 50 ft. range for internal active sampling pump
• Three standard alarms include vibration, visual, and audible alarm modes
• TWA and STEL exposure alarms along with lunch-break mode
• Lightweight at only 12.3 ounces
• Auto-calibration
• Circuit checking and calibration reminder complete with lockout option
• Rapid charging to full in under 90 minutes
• Large, glove friendly buttons
• Protective rubber housing and IP-67 water and dust protection
• Up to 600 hours of data logging with alarm trends
• Intrinsically safe

Intrinsically safe and built with petrochemical (oil rig/refinery) and waste water treatment facility workers in mind, the GX-2012 is ideal for tank cleaners and technical rescue workers too.
