GasAlert Extreme Oxygen (O2) Single Gas Detector, 0-30.0 Percent Measuring Range, Yellow
The BW Technologies GAXT-X-DL-2 GasAlert oxygen (O2) single-gas detector is a handheld, single-gas detector that uses an electrochemical cell sensor to measure oxygen continuously, and that has audio, visual, and vibration alarms, which alert simultaneously when oxygen reaches either of two 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 and minimum gas level recorded within the previous 24-hour period, the time elapsed since reaching that maximum or minimum level, and the battery life remaining. It is operated and adjusted with a single push button. This detector is used to indicate potentially harmful high or low levels of oxygen 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 either of two limits: a low-alarm level, when oxygen reaches 19.5% by volume, and a high-alarm level, when oxygen reaches 22.5% by volume. Alarm set-points are user-adjustable. In low-alarm conditions, the audible alarm beeps, the visual alarm flashes, and the unit vibrates slowly. In high-alarm conditions, 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 oxygen in high-noise conditions. 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.
