GasWatch 2
The GasWatch 2 is a single-gas monitor that can be worn on the wrist like a watch. The GasWatch 2 monitors oxygen deficiency, carbon monoxide or hydrogen sulfide (Models GW-2X, GW-2H, and GW-2C, respectively), and provides vibrator, audible, and visual alarms in the presence of a dangerous gas condition. The GasWatch 2 can be worn either on the wrist, belt, or hard hat using the supplied watch band, optional belt clip or hard hat clip.
