The GasWatch 2 is the first single-gas monitor that can be comfortably worn on the wrist like a watch. It is a convenient, inexpensive, hands-free method of gas monitoring for personal protection from oxygen deficiency, carbon monoxide or hydrogen sulfide.
The built-in vibrator, audible, and visual alarms immediately alert the user to a dangerous gas condition.
The GasWatch 2 is controlled by a microprocessor for reliability and advanced capabilities. Some of these advanced capabilities include distinctive audible and visual alarms for dangerous gas conditions and malfunctions, a large digital readout with a manual backlight that also automatically lights in an alarm condition, as well as the display of PEAK, TWA, and STEL*) readings. The replacement sensors are inexpensive and easily field replaceable.

Equipped with a watchstrap, belt clip, hard hat clip, or alligator clip, the GasWatch 2 can be worn either on the wrist, belt, hard hat, or clipped to protective wear. The GasWatch 2 will operate for over 3,000 hours on one battery (about 1 year normal use).
And yes, GasWatch 2 even tells the time!
