GasAlert Extreme
Single Gas Monitor for H2S, CO, O2, SO2, Cl2, HCN, NO2, NH3, PH3, ETO, ClO2, O3, or NO

Compact and affordable GasAlert Extreme detectors are available for a wide variety of atmospheric hazards. The GasAlert Extreme is highly water-resistant, with an IP 66/67 fully immersible, EMI / RFI resistant housing, built-in concussion-proof boot, and heavy-duty stainless steel, alligator-style belt clip. An extra loud audible alarm, flashing LED light bars, and built-in vibrator alert users to hazardous conditions. The large, easy-to-read display includes a built-in backlight that ensures readings are legible even in dim light conditions. An easily changed 3V camera battery provides up to two years of continuous operation.

The GasAlert Extreme clearly advises the gas hazard present – Low, High, TWA and STEL gas alarm. Recorded TWA, STEL and Peak exposures can be displayed on demand.

GasAlert Extreme detectors are optionally available with datalogging and multi-language support. Datalogging detectors include a built-in IR COM port for automatic data transfer to a computer or MicroDock II docking station module. No wires necessary!

The GasAlert Extreme continues the proud BW Technologies product tradition of cutting-edge features, trouble-free operation, durability and the lowest cost of ownership of any single-gas detector on the market today.
