The Gas Watch is the first single-gas monitor
that can be comfortably worn on the wrist like a watch. The Gas Watch 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 Gas Watch 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 Gas Watch can be worn
either on the wrist, belt, or hard hat.
The Gas Watch will operate for over 3000 hours on one battery (about 1 year
normal use). And yes, the Gas Watch even tells the time!
