Product Literature

The GasWatch 2 is the first single-gas
monitor that can be comfortably worn on the wrist like a watch.
The GasWatch 2 is a convenient, inexpensive, hands-free method
of gas monitoring for personal protection of oxygen deficiency,
carbon monoxide or 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 a watch band, optional belt clip or hard hat
clip, the GasWatch 2 can be worn either on the wrist, belt, or
hard hat.
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!
