After 60 years of breakthroughs in gas detection and sensor technology, RKI is proud to introduce the smallest and most affordable 4-gas monitor in the world, the GX-2001. Weighing only 6 ounces and about the size of a pager (2.8" H x 2.2" W x 1.1" D), the GX-2001 simultaneously monitors combustibles, oxygen, carbon monoxide, and hydrogen sulfide. The GX-2001 is armed with standard features like autocalibration, datalogging, rechargeable Ni-MH batteries, a unique vibration alarm, STEL / TWA readings, peak hold and auto backlighting at alarm on a large LCD display, and it even tells the time. All of these controls and features are operated through 3 simple glow in the dark buttons. Utilizing either of the GX-2001's chargers, the standard charger or datalogging / charger station, it's Ni-MH batteries will fully recharge in 90 minutes. Also available is the datalogging software program which is Windows 95, 98, ME compatible.

The GX-2001 is also designed around the world’s smallest gas sensors. Utilizing catalytic combustion, electrochemical and galvanic sensor technologies, each miniaturized sensor is manufactured with the same high quality control that has made Riken sensors and instruments the most reliable and long lasting monitoring devices in the industry.
