Part Number: 72-0314


RKI is proud to offer the smallest and lightest 4-gas monitor in the world, the GX-2009. Weighing only 130g it fits in the palm of your hand. The GX- 2009 simultaneously monitors and displays combustibles, oxygen, carbon monoxide, and hydrogen sulfide. The GX-2009 represents the latest evolution of gas detection technology.

List of Benefits

  • Simultaneous detection of 4 gases
  • Smallest / Lightest 4 gas monitor on the market
  • Dual audible alarm ports
  • 3 visual alarm LED’s
  • Vibration alarm
  • IP-67 Water resistant/dustproof
  • Calibration and bump test lock out or reminder controls
  • Large capacity data logging standard
  • 20 hours of operation (NiMH batteries)
  • Large LCD display screen
  • Automatic backlighting at alarm
  • Impact resistant rubber overmold body
  • STEL and TWA readouts
  • Intrinsically safe, CSA, C/US classified IECEx / ATEX approved (optional MSHA version available)
  • 2 year warranty

Advancements include dual audible alarm ports and alarm LED’s on 3 sides of the instrument, so that alarm conditions are obvious from multiple perspectives especially in high noise environments. Other features include a water resistant and dustproof design with IP 67 rating, an impact resistant rubber over-mold body that is RFI resistant, and a large capacity data logging system included as standard. Other standard features are vibration alarm, auto-calibration, calibration and bump test lock out or reminder control, STEL / TWA readings, peak hold, auto backlighting at alarm on a large LCD display, and it even tells the time! All of these controls and features are operated through 2 simple glove friendly buttons. The NiMH battery set will operate for 20 hours and will fully charge in 3 hours. A huge capacity data logging function is a standard feature on all GX-2009 instruments. The data logging software will store up to 100 calibration records and is Windows XP, 7, 8, and 10. The GX-2009 is also functional with the SDM-2009 single calibration station and the Data Cal 2000 instrument maintenance system.

The GX-2009 is designed around compact and proven sensors, utilizing catalytic combustion, electrochemical and galvanic sensor technologies. Each miniaturized sensor is manufactured with the same high quality control that hasmade GasTech sensors and instruments the most reliable and long lasting monitoring devices in the industry.
