The BW Technologies GAXT-V-DL GasAlert chlorine dioxide (ClO2) single-gas detector is a handheld, single-gas detector that uses an electrochemical cell sensor to measure chlorine dioxide (ClO2) continuously, and that has audio, visual, and vibration alarms, which alert simultaneously when ClO2 reaches any of four preset levels. The detector has an alphanumeric LCD screen that can be adjusted by the user to show the gas type monitored, the two alarm set-points, the alarm type, the maximum gas level recorded within the previous 24-hour period, the time elapsed since reaching that maximum level, and the battery life remaining. It is operated and adjusted with a single push button. This detector is used to indicate potentially harmful levels of ClO2 gas 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. Alarm set-points are user-adjustable. In low-alarm conditions and when the TWA is exceeded, the audible alarm beeps, the visual alarm flashes, and the unit vibrates slowly. In high-alarm conditions and when the STEL is exceeded, the audible alarm beeps, the visual alarm flashes, and the unit vibrates quickly. The three bright, wide-angle visual alarm bars and the built-in vibration alarm help alert the user to potentially dangerous
