- Four- detector for surveying levels of H2S, oxygen (O2), carbon monoxide (CO), and combustibles in natural and industrial environments, and in other personal safety, training, research, and ambient air monitoring applications.
- Electro cell sensor measures H2S and carbon monoxide levels in ppm, capillary-pore fuel cell measures oxygen in percent by volume, and catalytic bead combustible sensor measures explosive es in percent LEL.
- Audio, visual, and vibration alarms alert simultaneously when ambient H2S, oxygen, carbon monoxide, and combustible es reach preset low, high, TWA, or STEL levels.
- LCD screen shows up to four ambient concentrations, battery level, alarm condition, and the status of calibration, bump, and sensor self-tests.
- Integrated diaphragm pump allows for localized sampling of the atmosphere for more precise readings than those generated through diffusion.
The BW Technologies XT-XWHM-Y-NA AlertMax XT II 4- detector
with pump is a handheld, four- detector that uses an
electro cell sensor to monitor ambient H2S and carbon
monoxide (CO), a capillary pore fuel cell to measure oxygen
levels, and a catalytic bead sensor to monitor ambient
combustible es continuously. It has audio, visual, and
vibration alarms, which alert simultaneously when es reach any
of four preset levels. The integrated diaphragm pump allows for
localized sampling of the atmosphere for more precise readings
than those generated through diffusion. The detector has an
alphanumeric LCD screen that shows real-time concentration of
four monitored es, 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 es naturally occurring in the
environment; 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 set to alert to when 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 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. The 95 dB audible
alarm sounds at different speeds to indicate the alarm type, and
the three bright, wide-angled LED alarm bars and the built-in
vibration alarm help alert the user to potentially dangerous
levels of es in high-noise conditions. The detector logs and
retains data of the 10 most recent exposure events, which it
can transmit via an infrared Datalink USB adapter to a personal
computer (both sold separately).
This product is powered by a replaceable AA alkaline battery that
provides up to 14 hours of operational life. 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 during operation. 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-ed alligator clip to allow
the unit to be worn on a belt, waistband, or lapel, and built in
concussion-proof housing 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 2004/108/EC for electromagnetic compatibility of
electric and electronic equipment, 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, Division I, Group A, B, C , and D. It has an ingress
protection (IP) rating of 66/67.

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.
