Bw Technologies Gasalert Quattroâ 4 Gas Monitor

The BW Technologies QT-XWHM-A-Y-NA GasAlertQuattro 4-gas detector with alkaline battery is a handheld, four-gas detector that uses an electrochemical cell sensor to monitor ambient H2S, oxygen (O2), and carbon monoxide (CO) levels, and a catalytic bead sensor to monitor ambient combustible gases continuously, and that has audio, visual, and vibration alarms, which alert simultaneously when gases reach any of four preset levels. The detector has an alphanumeric LCD screen that shows 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.
