Details

The GX-2009 is the world’s smallest and lightest personal 4-gas monitor made by Riken Keiki, Japan. Weighing only 130 grams, it fits in the palm of your hand. The GX-2009 represents the latest evolution of gas detection technology. The GX-2009 simultaneously monitors and displays combustibles, Oxygen (O2), Carbon Monoxide (CO2), and Hydrogen Sulphide (H2S). All in a compact 70(H) x 75(L) x 25(D)mm (approx.) size.

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 dust-proof 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.

GX-2009 FeaturesThe GX-2009 is designed around Riken Keiki’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 Riken Keiki’s sensors and instruments the most reliable and long lasting monitoring devices in the industry.

Optional five gang multi-charger available.GX-2009 Multiple Linked Chargers

GX-2009-calibration-stationThe SDM-2009 is a single module calibration station for the GX-2009 gas monitor that can calibrate, bump test, charge, and archive data. It can work either independently of a PC or can be directly connected and controlled from a PC. Up to ten units can be connected together.
