The BW Technologies GA24XT-X AlertClip 2-year oxygen (O2 )
detector is a handheld, single- detector that uses an
electro cell sensor to monitor oxygen levels consistently
for up to two years without requiring calibration, recharging, or
battery replacement, and that has audio, visual, and vibration
alarms, which alert simultaneously when oxygen reaches the preset
low or high alarm levels. The detector has an alphanumeric LCD
screen that can be adjusted by the user to show the type
monitored, the two alarm set-points, the alarm level (low or
high), the maximum and minimum level recorded within the
previous 24-hour period, the time elapsed since reaching that
maximum or minimum level, and the detector life remaining, as
well as whether or not a self-test is required. It is operated
and adjusted with a single push button. This detector is used to
indicate potentially harmful levels of oxygen in a variety of
occupational settings such as petroleum refineries, tanneries,
sewage facilities, and paper mills; and in other
personal safety, educational, and ambient monitoring
applications.
This detector is factory-set to alert a low-alarm condition when
the level of oxygen reaches 19.5% and a high-alarm condition when
oxygen reaches 23.5%. In low-alarm conditions, the audible alarm
beeps once, the visual alarm flashes, and the unit vibrates once
per second. In high-alarm conditions, the audible alarm beeps
twice, the visual alarm flashes two times, and the unit vibrates
twice per second. 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 alarm deactivates when the level returns to an acceptable
range. Once the exposure alarm initiates, the detector
records the maximum exposure and the time since reaching that
maximum exposure for up to 24 hours. The detector logs and
retains data of the 10 most recent exposure events, which it
can transmit via built-in infrared sensor to a thermal printer
(sold separately), or via an infrared Datalink USB adapter to a
personal computer (both sold separately).
To ensure performance, the detector tests its built-in lithium
battery automatically every two hours, and the LCD prompts the
user daily to initiate a full-function self-test. The self-test
verifies the integrity of the battery, sensor, and circuitry. The
detector also features an automatic shutdown mode for additional
safety, which activates after five consecutive battery test
failures, three consecutive self-test failures, or when the
detector has reached the end of its two-year life.
This detector comes with a back-ed 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 94/9/EC concerning equipment or protective systems
intended for use in potentially explosive atmospheres, and it
meets Underwriters Laboratory (UL) 913 for an Intrinsically Safe
Apparatus and Associated Apparatus for Use in Class I, II, and
III, Division I, Hazardous (Classified) Locations.

A detector is a safety device that detects and monitors
various toxic, combustible, and flammable ses in an area, and
which can also register a decrease in ambient oxygen.
detectors can be portable or stationary, and are typically
classified by their detection methods, which include catalytic,
electro-, point infrared, open-path infrared,
semiconductor, thermal path conductor, and paper tape detection.
detectors are first calibrated to known ses that serve as
a reference points. Their sensors can then be used to measure
ambient concentrations in comparison to the calibration
ses. When concentrations exceed a pre-set limit, an alarm
or signal is triggered, alerting the user to potential danger.
Pre-set limits often include a low-alarm level, indicating a
concentration that poses a moderate danger; a high-alarm level,
indicating a concentration that poses a large danger; a
short-term exposure limit (STEL), the maximum concentration
to which workers can be exposed continuously for a short period
of time without serious risk of harm, and time-weighted average
(TWA) limit, the maximum average exposure personnel can
experience over the course of an eight-hour work shift without
serious risk of harm. Most detectors also feature LCD screens
that provide a variety of information including ses detected
and their concentrations, pre-set exposure limits, and battery
level.
detectors have a variety of industrial and governmental
applications, such as in fire and rescue, mining, construction,
petroleum refineries, tanneries, sewage facilities, and
paper mills. Portable detectors are typically used to monitor
the air around personnel, are worn on clothing or on belts or
harnesses, and are powered with rechargeable or disposable
batteries. They generally require periodic calibration, testing,
and battery recharging or replacement, although some fixed-life
detectors are designed to perform for a number of years without
calibration or battery replacement before being dided.
Stationary detectors are typically powered electrically and
ed near the process area of a or control room. They
also require periodic service, testing, and calibration.
BW Technologies by Honeywell manufactures and distributes
portable and fixed monitoring equipment for use in a wide
range of industries. The company, founded in 1987, is based in
Canada in Calgary, Alberta.
