With RKI's GasWatch GW-2H, Hydrogen Sulfide monitoring is as easy as putting on your hard hat!
Features & Applications:
The GasWatch 2 will operate for over 3000 hours on one battery (about 1 year normal use), making it the ideal, inexpensive hands free monitor for gas monitoring for personal protection from dangerous hydrogen sulfide levels. The distinctive audible and visual alarms immediately alert the user of a dangerous gas condition, and the large digital readout with a manual backlight displays PEAK, TWA, and STEL readings. Replacement sensors for this unit are also inexpensive, have a life expectancy of about 2 years and can be easily replaced in the field. This unit is equipped with hard hat clip, and even tells the time!
