Smallest Four Gas Personal Monitor

GX-2001 Gas MonitorAfter 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.
