   RKI is proud to offer the smallest and lightest 4-gas monitor in the world, the GX-2009. Weighing only 4.6 ounces, it fits in the palm of your hand (2.75' H x 2.95' L x .98' D). 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. 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 waterproof 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 a standard feature.   FeatureSimultaneous detection of 4 gases, LEL, O2, H2S & COSmallest / Lightest 4 gas monitor on the market ° 2.7” H x 3” W x 1” D, 4.6 ozDual audible alarm ports (95 db @ 30 cm)3 visual alarm LED’sVibration alarmIP-67 Waterproof/dustproof designCalibration lock out or reminder controlsLarge capacity data logging standard

- 100 calibration records20 hours of operation (NiMH batteries)Large LCD display screenAutomatic backlighting at alarmImpact resistant over-mold body, RFI shielded bodySTEL and TWA readoutsIntrinsically safe, CSA, C/US classified, IECEx / ATEX approved2 year warrantyOther standard features are vibration alarm, autocalibration, calibration 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 glow-in-the dark, 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, and will store up to 8 alarm trend sessions where readings are recorded 30 minutes before and after an alarm event. The data logging has a 3,600 data point capacity with a log time range of 10 to 300 hours based on programmable interval times. The data logging software will also store up to 100 calibration records and is Windows XP and Vista compatible. The GX-2009 is also functional with the Data Cal 2000 instrument maintenance system and the SM-2009U single calibration station (available in 2009). Application:Personal monitoringConfined spacesRefineries/petrochemicalUtilitiesHazardous materialWater/wastewaterFire servicesConstructionSpecification:The GX-2009 is designed around RKI's compact and proven sensors, utilizing catalytic combustion, electrochemical and galvanic sensor technologies. Each miniaturized sensor is manufactured with the same high quality control that has made RKI sensors and instruments the most reliable and long lasting monitoring devices in the industry.
