BW GasAlert Extreme detectors are widely popular for the detection of a variety of atmospheric hazards. This unit provides quick and accurate readings of Hydrogen Sulfide, alerting you to hazardous conditions via an extra-loud audible alarm, flashing LED light bars, and a built-in vibrator. The unit is highly water-resistant, with an IP 66/67 fully immersible, and is designed with an EMI / RFI resistant housing, a built-in concussion-proof boot, and a heavy-duty, stainless steel, alligator style belt-clip. The BW Gas Alert Extreme delivers up to two years of continuous operation with a 3V camera battery.
