The GasWatch 2 is the first single-gas monitor that can be comfortably worn on the wrist like a watch. It's a convenient, inexpensive, hands-free method of gas monitoring for personal protection of hydrogen sulfide. The built in vibrator, audible, and visual alarms immediately alert the user of 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, easily field replaceable and have a life expectancy of about 2 years. Equipped with belt clip.
The GasWatch 2 will operate for over 3000 hours on one battery (about 1 year normal use). And yes, the GasWatch 2 even tells the time!
