About BW Technologies GAXT-H-DL GasAlert Extreme Hydrogen
The BW Technologies GAXT-H-DL GasAlert hydrogen sulfide (H2S) single-gas detector is a handheld, single-gas detector that uses an electrochemical cell sensor to measure hydrogen sulfide (H2S) continuously, and that has audio, visual, and vibration alarms, which alert simultaneously when H2S 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 H2S 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 levels of H2S in high-noise conditions. Once the gas exposure alarm initiates, the detector records the maximum gas exposure and the time since reaching that maximum gas exposure for up to 24 hours. The detector logs and retains data of the 10 most recent gas exposure events, which it can transmit via an infrared Datalink USB adapter to a personal computer (both sold separately). To ensure performance, the detector tests its sensor integrity, circuitry, and audible and visual alarms upon activation. It tests its battery upon activation and continuously every 0.5 second. The detector also features an automatic shutdown mode for additional safety, which activates when the detector fails its self-test. This detector comes with a back-mounted alligator clip to allow the unit to be worn on a belt, waistband, or lapel, and a concussion-resistant boot to help protect it against damage. It is water resistant, and is compatible with the BW Technologies MicroDock II automatic test system (sold separately). It has a European Conformity (CE) and ATEX certification in accordance with Directive 89/336/EEC for safety of electrical and electronic devices, and it is classified by Underwriters Laboratory (UL) to U.S. and Canadian standards as an Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I,II, and III, Division I, Group A, B, C, and D. It has an ingress protection (IP) rating of 66/67.
