BW Technologies XT-XWHM-Y-NA GasAlertMax XT II 4-Gas Detector with Pump, Combustible, O2, H2S and CO, Yellow by BW Technologies

Four-gas detector for surveying levels of H2S, oxygen (O2), carbon monoxide (CO), and combustibles in natural and industrial environments, and in other personal safety, training, research, and ambient air monitoring applications

Electrochemical cell sensor measures H2S and carbon monoxide levels in ppm, capillary-pore fuel cell measures oxygen in percent by volume, and catalytic bead combustible sensor measures explosive gases in percent LEL

Audio, visual, and vibration alarms alert simultaneously when ambient H2S, oxygen, carbon monoxide, and combustible gases reach preset low, high, TWA, or STEL levels

LCD screen shows up to four ambient gas concentrations, battery level, alarm condition, and the status of calibration, bump, and sensor self-tests

Integrated diaphragm pump allows for localized sampling of the atmosphere for more precise readings than those generated through diffusion

The BW Technologies XT-XWHM-Y-NA GasAlertMax XT II 4-gas detector with the pump is a handheld, a four-gas detector that uses an electrochemical cell sensor to monitor ambient H2S and carbon monoxide (CO), a capillary pore fuel cell to measure oxygen levels, and a catalytic bead sensor to monitor ambient combustible gases continuously. It has audio, visual, and vibration alarms, which alert simultaneously when gases reach any of four preset levels. The integrated diaphragm pump allows for localized sampling of the atmosphere for more precise readings than those generated through diffusion. The detector has an alphanumeric LCD screen that shows the real-time concentration of four monitored gases, the alarm type, the calibration requirements, the self-test pass or fail, and the battery life remaining. The LCD also displays a constant flashing heartbeat icon to indicate normal functioning. The detector is operated and adjusted with a single push button. It is used to indicate potentially harmful levels of gases naturally occurring in the environment; in a variety of occupational settings such as petroleum refineries, tanneries, sewage treatment facilities, and paper mills; and in other personal safety, educational, and ambient monitoring applications. This detector is set to alert to when gas levels reach any of four limits: a low-alarm level, indicating moderate danger; a high-alarm level, indicating significant danger; a short-term exposure limit (STEL), the maximum gas concentration to which workers can be exposed continuously for a short period of time without serious risk; and a time-weighted average (TWA) limit, the maximum average exposure that personnel can experience over an eight-hour work shift without serious risk Warning: This product can expose you to chemicals which is [are] known to the State of California to cause cancer and birth defects or other reproductive harm.
