The GX-2001 simultaneously monitors combustibles, oxygen, carbon monoxide, and hydrogen sulfide. It is armed with standard features like a vibration alarm, autocalibration. PEAK-, STEL- and TWA readings, datalogging 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 the standard charger or datalogging charger station, the Ni-MH battery pack will operate for 18 hours and fully recharge in 90 minutes.
The GX-2001 is designed around the world´s smallest gas sensors. Each miniaturized sensor in 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.
